Get shard allocation information

GET /_cat/allocation/{node_id}

Get a snapshot of the number of shards allocated to each data node and their disk space.

IMPORTANT: CAT APIs are only intended for human consumption using the command line or Kibana console. They are not intended for use by applications.

Path parameters

  • node_id string | array[string] Required

    A comma-separated list of node identifiers or names used to limit the returned information.

Query parameters

  • bytes string

    The unit used to display byte values.

    Values are b, kb, mb, gb, tb, or pb.

  • h string | array[string]

    List of columns to appear in the response. Supports simple wildcards.

  • s string | array[string]

    List of columns that determine how the table should be sorted. Sorting defaults to ascending and can be changed by setting :asc or :desc as a suffix to the column name.

  • local boolean

    If true, the request computes the list of selected nodes from the local cluster state. If false the list of selected nodes are computed from the cluster state of the master node. In both cases the coordinating node will send requests for further information to each selected node.

  • Period to wait for a connection to the master node.

Clear cluster voting config exclusions Added in 7.0.0

DELETE /_cluster/voting_config_exclusions

Remove master-eligible nodes from the voting configuration exclusion list.

External documentation

Query parameters

  • Period to wait for a connection to the master node.

  • Specifies whether to wait for all excluded nodes to be removed from the cluster before clearing the voting configuration exclusions list. Defaults to true, meaning that all excluded nodes must be removed from the cluster before this API takes any action. If set to false then the voting configuration exclusions list is cleared even if some excluded nodes are still in the cluster.

Get node statistics

GET /_nodes/{node_id}/stats/{metric}

Get statistics for nodes in a cluster. By default, all stats are returned. You can limit the returned information by using metrics.

Path parameters

  • node_id string | array[string] Required

    Comma-separated list of node IDs or names used to limit returned information.

  • metric string | array[string] Required

    Limit the information returned to the specified metrics

Query parameters

  • completion_fields string | array[string]

    Comma-separated list or wildcard expressions of fields to include in fielddata and suggest statistics.

  • fielddata_fields string | array[string]

    Comma-separated list or wildcard expressions of fields to include in fielddata statistics.

  • fields string | array[string]

    Comma-separated list or wildcard expressions of fields to include in the statistics.

  • groups boolean

    Comma-separated list of search groups to include in the search statistics.

  • If true, the call reports the aggregated disk usage of each one of the Lucene index files (only applies if segment stats are requested).

  • level string

    Indicates whether statistics are aggregated at the cluster, index, or shard level.

    Values are cluster, indices, or shards.

  • timeout string

    Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.

  • types array[string]

Check for a document source Added in 5.4.0

HEAD /{index}/_source/{id}

Check whether a document source exists in an index. For example:

HEAD my-index-000001/_source/1

A document's source is not available if it is disabled in the mapping.

External documentation

Path parameters

  • index string Required

    A comma-separated list of data streams, indices, and aliases. It supports wildcards (*).

  • id string Required

    A unique identifier for the document.

Query parameters

  • The node or shard the operation should be performed on. By default, the operation is randomized between the shard replicas.

  • realtime boolean

    If true, the request is real-time as opposed to near-real-time.

  • refresh boolean

    If true, the request refreshes the relevant shards before retrieving the document. Setting it to true should be done after careful thought and verification that this does not cause a heavy load on the system (and slow down indexing).

  • routing string

    A custom value used to route operations to a specific shard.

  • _source boolean | string | array[string]

    Indicates whether to return the _source field (true or false) or lists the fields to return.

  • _source_excludes string | array[string]

    A comma-separated list of source fields to exclude in the response.

  • _source_includes string | array[string]

    A comma-separated list of source fields to include in the response.

  • version number

    The version number for concurrency control. It must match the current version of the document for the request to succeed.

  • The version type.

    Values are internal, external, external_gte, or force.

Create or update a document in an index

POST /{index}/_doc

Add a JSON document to the specified data stream or index and make it searchable. If the target is an index and the document already exists, the request updates the document and increments its version.

NOTE: You cannot use this API to send update requests for existing documents in a data stream.

If the Elasticsearch security features are enabled, you must have the following index privileges for the target data stream, index, or index alias:

  • To add or overwrite a document using the PUT /<target>/_doc/<_id> request format, you must have the create, index, or write index privilege.
  • To add a document using the POST /<target>/_doc/ request format, you must have the create_doc, create, index, or write index privilege.
  • To automatically create a data stream or index with this API request, you must have the auto_configure, create_index, or manage index privilege.

Automatic data stream creation requires a matching index template with data stream enabled.

NOTE: Replica shards might not all be started when an indexing operation returns successfully. By default, only the primary is required. Set wait_for_active_shards to change this default behavior.

Automatically create data streams and indices

If the request's target doesn't exist and matches an index template with a data_stream definition, the index operation automatically creates the data stream.

If the target doesn't exist and doesn't match a data stream template, the operation automatically creates the index and applies any matching index templates.

NOTE: Elasticsearch includes several built-in index templates. To avoid naming collisions with these templates, refer to index pattern documentation.

If no mapping exists, the index operation creates a dynamic mapping. By default, new fields and objects are automatically added to the mapping if needed.

Automatic index creation is controlled by the action.auto_create_index setting. If it is true, any index can be created automatically. You can modify this setting to explicitly allow or block automatic creation of indices that match specified patterns or set it to false to turn off automatic index creation entirely. Specify a comma-separated list of patterns you want to allow or prefix each pattern with + or - to indicate whether it should be allowed or blocked. When a list is specified, the default behaviour is to disallow.

NOTE: The action.auto_create_index setting affects the automatic creation of indices only. It does not affect the creation of data streams.

Optimistic concurrency control

Index operations can be made conditional and only be performed if the last modification to the document was assigned the sequence number and primary term specified by the if_seq_no and if_primary_term parameters. If a mismatch is detected, the operation will result in a VersionConflictException and a status code of 409.

Routing

By default, shard placement — or routing — is controlled by using a hash of the document's ID value. For more explicit control, the value fed into the hash function used by the router can be directly specified on a per-operation basis using the routing parameter.

When setting up explicit mapping, you can also use the _routing field to direct the index operation to extract the routing value from the document itself. This does come at the (very minimal) cost of an additional document parsing pass. If the _routing mapping is defined and set to be required, the index operation will fail if no routing value is provided or extracted.

NOTE: Data streams do not support custom routing unless they were created with the allow_custom_routing setting enabled in the template.

Distributed

The index operation is directed to the primary shard based on its route and performed on the actual node containing this shard. After the primary shard completes the operation, if needed, the update is distributed to applicable replicas.

Active shards

To improve the resiliency of writes to the system, indexing operations can be configured to wait for a certain number of active shard copies before proceeding with the operation. If the requisite number of active shard copies are not available, then the write operation must wait and retry, until either the requisite shard copies have started or a timeout occurs. By default, write operations only wait for the primary shards to be active before proceeding (that is to say wait_for_active_shards is 1). This default can be overridden in the index settings dynamically by setting index.write.wait_for_active_shards. To alter this behavior per operation, use the wait_for_active_shards request parameter.

Valid values are all or any positive integer up to the total number of configured copies per shard in the index (which is number_of_replicas+1). Specifying a negative value or a number greater than the number of shard copies will throw an error.

For example, suppose you have a cluster of three nodes, A, B, and C and you create an index index with the number of replicas set to 3 (resulting in 4 shard copies, one more copy than there are nodes). If you attempt an indexing operation, by default the operation will only ensure the primary copy of each shard is available before proceeding. This means that even if B and C went down and A hosted the primary shard copies, the indexing operation would still proceed with only one copy of the data. If wait_for_active_shards is set on the request to 3 (and all three nodes are up), the indexing operation will require 3 active shard copies before proceeding. This requirement should be met because there are 3 active nodes in the cluster, each one holding a copy of the shard. However, if you set wait_for_active_shards to all (or to 4, which is the same in this situation), the indexing operation will not proceed as you do not have all 4 copies of each shard active in the index. The operation will timeout unless a new node is brought up in the cluster to host the fourth copy of the shard.

It is important to note that this setting greatly reduces the chances of the write operation not writing to the requisite number of shard copies, but it does not completely eliminate the possibility, because this check occurs before the write operation starts. After the write operation is underway, it is still possible for replication to fail on any number of shard copies but still succeed on the primary. The _shards section of the API response reveals the number of shard copies on which replication succeeded and failed.

No operation (noop) updates

When updating a document by using this API, a new version of the document is always created even if the document hasn't changed. If this isn't acceptable use the _update API with detect_noop set to true. The detect_noop option isn't available on this API because it doesn’t fetch the old source and isn't able to compare it against the new source.

There isn't a definitive rule for when noop updates aren't acceptable. It's a combination of lots of factors like how frequently your data source sends updates that are actually noops and how many queries per second Elasticsearch runs on the shard receiving the updates.

Versioning

Each indexed document is given a version number. By default, internal versioning is used that starts at 1 and increments with each update, deletes included. Optionally, the version number can be set to an external value (for example, if maintained in a database). To enable this functionality, version_type should be set to external. The value provided must be a numeric, long value greater than or equal to 0, and less than around 9.2e+18.

NOTE: Versioning is completely real time, and is not affected by the near real time aspects of search operations. If no version is provided, the operation runs without any version checks.

When using the external version type, the system checks to see if the version number passed to the index request is greater than the version of the currently stored document. If true, the document will be indexed and the new version number used. If the value provided is less than or equal to the stored document's version number, a version conflict will occur and the index operation will fail. For example:

PUT my-index-000001/_doc/1?version=2&version_type=external
{
  "user": {
    "id": "elkbee"
  }
}

In this example, the operation will succeed since the supplied version of 2 is higher than the current document version of 1.
If the document was already updated and its version was set to 2 or higher, the indexing command will fail and result in a conflict (409 HTTP status code).

A nice side effect is that there is no need to maintain strict ordering of async indexing operations run as a result of changes to a source database, as long as version numbers from the source database are used.
Even the simple case of updating the Elasticsearch index using data from a database is simplified if external versioning is used, as only the latest version will be used if the index operations arrive out of order.
External documentation

Path parameters

  • index string Required

    The name of the data stream or index to target. If the target doesn't exist and matches the name or wildcard (*) pattern of an index template with a data_stream definition, this request creates the data stream. If the target doesn't exist and doesn't match a data stream template, this request creates the index. You can check for existing targets with the resolve index API.

Query parameters

  • Only perform the operation if the document has this primary term.

  • Only perform the operation if the document has this sequence number.

  • True or false if to include the document source in the error message in case of parsing errors.

  • op_type string

    Set to create to only index the document if it does not already exist (put if absent). If a document with the specified _id already exists, the indexing operation will fail. The behavior is the same as using the <index>/_create endpoint. If a document ID is specified, this paramater defaults to index. Otherwise, it defaults to create. If the request targets a data stream, an op_type of create is required.

    Values are index or create.

  • pipeline string

    The ID of the pipeline to use to preprocess incoming documents. If the index has a default ingest pipeline specified, then setting the value to _none disables the default ingest pipeline for this request. If a final pipeline is configured it will always run, regardless of the value of this parameter.

  • refresh string

    If true, Elasticsearch refreshes the affected shards to make this operation visible to search. If wait_for, it waits for a refresh to make this operation visible to search. If false, it does nothing with refreshes.

    Values are true, false, or wait_for.

  • routing string

    A custom value that is used to route operations to a specific shard.

  • timeout string

    The period the request waits for the following operations: automatic index creation, dynamic mapping updates, waiting for active shards.

    This parameter is useful for situations where the primary shard assigned to perform the operation might not be available when the operation runs. Some reasons for this might be that the primary shard is currently recovering from a gateway or undergoing relocation. By default, the operation will wait on the primary shard to become available for at least 1 minute before failing and responding with an error. The actual wait time could be longer, particularly when multiple waits occur.

  • version number

    An explicit version number for concurrency control. It must be a non-negative long number.

  • The version type.

    Values are internal, external, external_gte, or force.

  • wait_for_active_shards number | string

    The number of shard copies that must be active before proceeding with the operation. You can set it to all or any positive integer up to the total number of shards in the index (number_of_replicas+1). The default value of 1 means it waits for each primary shard to be active.

  • If true, the destination must be an index alias.

Get index templates Added in 7.9.0

GET /_index_template

Get information about one or more index templates.

Query parameters

  • local boolean

    If true, the request retrieves information from the local node only. Defaults to false, which means information is retrieved from the master node.

  • If true, returns settings in flat format.

  • Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

  • If true, returns all relevant default configurations for the index template.

Get index settings

GET /{index}/_settings

Get setting information for one or more indices. For data streams, it returns setting information for the stream's backing indices.

Path parameters

  • index string | array[string] Required

    Comma-separated list of data streams, indices, and aliases used to limit the request. Supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

Query parameters

  • If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices. For example, a request targeting foo*,bar* returns an error if an index starts with foo but no index starts with bar.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden.

  • If true, returns settings in flat format.

  • If false, the request returns an error if it targets a missing or closed index.

  • If true, return all default settings in the response.

  • local boolean

    If true, the request retrieves information from the local node only. If false, information is retrieved from the master node.

  • Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

          • If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

          • Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern .*-{date_format}-\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.

          • prefer_ilm boolean | string

            Preference for the system that manages a data stream backing index (preferring ILM when both ILM and DLM are applicable for an index).

        • creation_date_string string | number

          A date and time, either as a string whose format can depend on the context (defaulting to ISO 8601), or a number of milliseconds since the Epoch. Elasticsearch accepts both as input, but will generally output a string representation.

        • uuid string

          Hide mapping attributes Show mapping attributes object
          • coerce boolean
          • Hide total_fields attributes Show total_fields attributes object
            • limit number | string

              The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

            • ignore_dynamic_beyond_limit boolean | string

              This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

          • depth object
            Hide depth attribute Show depth attribute object
            • limit number

              The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

          • Hide nested_fields attribute Show nested_fields attribute object
            • limit number

              The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

          • Hide nested_objects attribute Show nested_objects attribute object
            • limit number

              The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.

          • Hide field_name_length attribute Show field_name_length attribute object
            • limit number

              Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).

          • Hide dimension_fields attribute Show dimension_fields attribute object
            • limit number

              [preview] This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

          • source object

              • warn string

                A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

              • info string

                A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

            • limit number

              Number of outstanding bytes that may be consumed by indexing requests. When this limit is reached or exceeded, the node will reject new coordinating and primary operations. When replica operations consume 1.5x this limit, the node will reject new replica operations. Defaults to 10% of the heap.

            Any of:

            Values are fs, niofs, mmapfs, or hybridfs.

          • allow_mmap boolean

            You can restrict the use of the mmapfs and the related hybridfs store type via the setting node.store.allow_mmap. This is a boolean setting indicating whether or not memory-mapping is allowed. The default is to allow it. This setting is useful, for example, if you are in an environment where you can not control the ability to create a lot of memory maps so you need disable the ability to use memory-mapping.

          • If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value in milliseconds.

          • Set to true to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern .*-{date_format}-\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional. An index that was rolled over would normally match the full format, for example logs-2016.10.31-000002). If the index name doesn’t match the pattern, index creation fails.

          • Hide total_fields attributes Show total_fields attributes object
            • limit number | string

              The maximum number of fields in an index. Field and object mappings, as well as field aliases count towards this limit. The limit is in place to prevent mappings and searches from becoming too large. Higher values can lead to performance degradations and memory issues, especially in clusters with a high load or few resources.

            • ignore_dynamic_beyond_limit boolean | string

              This setting determines what happens when a dynamically mapped field would exceed the total fields limit. When set to false (the default), the index request of the document that tries to add a dynamic field to the mapping will fail with the message Limit of total fields [X] has been exceeded. When set to true, the index request will not fail. Instead, fields that would exceed the limit are not added to the mapping, similar to dynamic: false. The fields that were not added to the mapping will be added to the _ignored field.

          • depth object
            Hide depth attribute Show depth attribute object
            • limit number

              The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.

          • Hide nested_fields attribute Show nested_fields attribute object
            • limit number

              The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.

          • Hide nested_objects attribute Show nested_objects attribute object
            • limit number

              The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.

          • Hide field_name_length attribute Show field_name_length attribute object
            • limit number

              Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).

          • Hide dimension_fields attribute Show dimension_fields attribute object
            • limit number

Open a closed index

POST /{index}/_open

For data streams, the API opens any closed backing indices.

A closed index is blocked for read/write operations and does not allow all operations that opened indices allow. It is not possible to index documents or to search for documents in a closed index. This allows closed indices to not have to maintain internal data structures for indexing or searching documents, resulting in a smaller overhead on the cluster.

When opening or closing an index, the master is responsible for restarting the index shards to reflect the new state of the index. The shards will then go through the normal recovery process. The data of opened or closed indices is automatically replicated by the cluster to ensure that enough shard copies are safely kept around at all times.

You can open and close multiple indices. An error is thrown if the request explicitly refers to a missing index. This behavior can be turned off by using the ignore_unavailable=true parameter.

By default, you must explicitly name the indices you are opening or closing. To open or close indices with _all, *, or other wildcard expressions, change the action.destructive_requires_name setting to false. This setting can also be changed with the cluster update settings API.

Closed indices consume a significant amount of disk-space which can cause problems in managed environments. Closing indices can be turned off with the cluster settings API by setting cluster.indices.close.enable to false.

Because opening or closing an index allocates its shards, the wait_for_active_shards setting on index creation applies to the _open and _close index actions as well.

Path parameters

  • index string | array[string] Required

    Comma-separated list of data streams, indices, and aliases used to limit the request. Supports wildcards (*). By default, you must explicitly name the indices you using to limit the request. To limit a request using _all, *, or other wildcard expressions, change the action.destructive_requires_name setting to false. You can update this setting in the elasticsearch.yml file or using the cluster update settings API.

Query parameters

  • If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.

  • If false, the request returns an error if it targets a missing or closed index.

  • Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

  • timeout string

    Period to wait for a response. If no response is received before the timeout expires, the request fails and returns an error.

  • wait_for_active_shards number | string

    The number of shard copies that must be active before proceeding with the operation. Set to all or any positive integer up to the total number of shards in the index (number_of_replicas+1).

Responses

POST /{index}/_open
curl \
 --request POST 'http://api.example.com/{index}/_open' \
 --header "Authorization: $API_KEY"
Response examples (200)
A successful response for opening an index.
{
  "acknowledged" : true,
  "shards_acknowledged" : true
}




















Refresh an index

POST /{index}/_refresh

A refresh makes recent operations performed on one or more indices available for search. For data streams, the API runs the refresh operation on the stream’s backing indices.

By default, Elasticsearch periodically refreshes indices every second, but only on indices that have received one search request or more in the last 30 seconds. You can change this default interval with the index.refresh_interval setting.

Refresh requests are synchronous and do not return a response until the refresh operation completes.

Refreshes are resource-intensive. To ensure good cluster performance, it's recommended to wait for Elasticsearch's periodic refresh rather than performing an explicit refresh when possible.

If your application workflow indexes documents and then runs a search to retrieve the indexed document, it's recommended to use the index API's refresh=wait_for query parameter option. This option ensures the indexing operation waits for a periodic refresh before running the search.

Path parameters

  • index string | array[string] Required

    Comma-separated list of data streams, indices, and aliases used to limit the request. Supports wildcards (*). To target all data streams and indices, omit this parameter or use * or _all.

Query parameters

  • If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.

  • If false, the request returns an error if it targets a missing or closed index.

Validate a query Added in 1.3.0

GET /_validate/query

Validates a query without running it.

Query parameters

  • If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices. This behavior applies even if the request targets other open indices.

  • all_shards boolean

    If true, the validation is executed on all shards instead of one random shard per index.

  • analyzer string

    Analyzer to use for the query string. This parameter can only be used when the q query string parameter is specified.

  • If true, wildcard and prefix queries are analyzed.

  • The default operator for query string query: AND or OR.

    Values are and, AND, or, or OR.

  • df string

    Field to use as default where no field prefix is given in the query string. This parameter can only be used when the q query string parameter is specified.

  • expand_wildcards string | array[string]

    Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.

  • explain boolean

    If true, the response returns detailed information if an error has occurred.

  • If false, the request returns an error if it targets a missing or closed index.

  • lenient boolean

    If true, format-based query failures (such as providing text to a numeric field) in the query string will be ignored.

  • rewrite boolean

    If true, returns a more detailed explanation showing the actual Lucene query that will be executed.

  • q string

    Query in the Lucene query string syntax.

Create an JinaAI inference endpoint Added in 8.18.0

PUT /_inference/{task_type}/{jinaai_inference_id}

Create an inference endpoint to perform an inference task with the jinaai service.

To review the available rerank models, refer to https://jina.ai/reranker. To review the available text_embedding models, refer to the https://jina.ai/embeddings/.

When you create an inference endpoint, the associated machine learning model is automatically deployed if it is not already running. After creating the endpoint, wait for the model deployment to complete before using it. To verify the deployment status, use the get trained model statistics API. Look for "state": "fully_allocated" in the response and ensure that the "allocation_count" matches the "target_allocation_count". Avoid creating multiple endpoints for the same model unless required, as each endpoint consumes significant resources.

Path parameters

  • task_type string Required

    The type of the inference task that the model will perform.

    Values are rerank or text_embedding.

  • jinaai_inference_id string Required

    The unique identifier of the inference endpoint.

application/json

Body

  • Hide chunking_settings attributes Show chunking_settings attributes object
    • The maximum size of a chunk in words. This value cannot be higher than 300 or lower than 20 (for sentence strategy) or 10 (for word strategy).

    • overlap number

      The number of overlapping words for chunks. It is applicable only to a word chunking strategy. This value cannot be higher than half the max_chunk_size value.

    • The number of overlapping sentences for chunks. It is applicable only for a sentence chunking strategy. It can be either 1 or 0.

    • strategy string

      The chunking strategy: sentence or word.

  • service string Required

    Value is jinaai.

  • service_settings object Required
    Hide service_settings attributes Show service_settings attributes object
    • api_key string Required

      A valid API key of your JinaAI account.

      IMPORTANT: You need to provide the API key only once, during the inference model creation. The get inference endpoint API does not retrieve your API key. After creating the inference model, you cannot change the associated API key. If you want to use a different API key, delete the inference model and recreate it with the same name and the updated API key.

      External documentation
    • model_id string

      The name of the model to use for the inference task. For a rerank task, it is required. For a text_embedding task, it is optional.

    • Hide rate_limit attribute Show rate_limit attribute object
    • Values are cosine, dot_product, or l2_norm.

  • Hide task_settings attributes Show task_settings attributes object
    • For a rerank task, return the doc text within the results.

    • task string

      Values are classification, clustering, ingest, or search.

    • top_n number

      For a rerank task, the number of most relevant documents to return. It defaults to the number of the documents. If this inference endpoint is used in a text_similarity_reranker retriever query and top_n is set, it must be greater than or equal to rank_window_size in the query.

Force buffered data to be processed Added in 5.4.0

POST /_ml/anomaly_detectors/{job_id}/_flush

The flush jobs API is only applicable when sending data for analysis using the post data API. Depending on the content of the buffer, then it might additionally calculate new results. Both flush and close operations are similar, however the flush is more efficient if you are expecting to send more data for analysis. When flushing, the job remains open and is available to continue analyzing data. A close operation additionally prunes and persists the model state to disk and the job must be opened again before analyzing further data.

Path parameters

  • job_id string Required

    Identifier for the anomaly detection job.

Query parameters

  • advance_time string | number

    Specifies to advance to a particular time value. Results are generated and the model is updated for data from the specified time interval.

  • If true, calculates the interim results for the most recent bucket or all buckets within the latency period.

  • end string | number

    When used in conjunction with calc_interim and start, specifies the range of buckets on which to calculate interim results.

  • skip_time string | number

    Specifies to skip to a particular time value. Results are not generated and the model is not updated for data from the specified time interval.

  • start string | number

    When used in conjunction with calc_interim, specifies the range of buckets on which to calculate interim results.

    1. Contains wildcard expressions and there are no data frame analytics jobs that match.
    2. Contains the _all string or no identifiers and there are no matches.
    3. Contains wildcard expressions and there are only partial matches.

    The default value returns an empty data_frame_analytics array when there are no matches and the subset of results when there are partial matches. If this parameter is false, the request returns a 404 status code when there are no matches or only partial matches.

  • from number

    Skips the specified number of data frame analytics jobs.

  • size number

    Specifies the maximum number of data frame analytics jobs to obtain.

  • verbose boolean

    Defines whether the stats response should be verbose.

            Hide hyperparameters attributes Show hyperparameters attributes object
            • alpha number

              Advanced configuration option. Machine learning uses loss guided tree growing, which means that the decision trees grow where the regularized loss decreases most quickly. This parameter affects loss calculations by acting as a multiplier of the tree depth. Higher alpha values result in shallower trees and faster training times. By default, this value is calculated during hyperparameter optimization. It must be greater than or equal to zero.

            • lambda number

              Advanced configuration option. Regularization parameter to prevent overfitting on the training data set. Multiplies an L2 regularization term which applies to leaf weights of the individual trees in the forest. A high lambda value causes training to favor small leaf weights. This behavior makes the prediction function smoother at the expense of potentially not being able to capture relevant relationships between the features and the dependent variable. A small lambda value results in large individual trees and slower training. By default, this value is calculated during hyperparameter optimization. It must be a nonnegative value.

            • gamma number

              Advanced configuration option. Regularization parameter to prevent overfitting on the training data set. Multiplies a linear penalty associated with the size of individual trees in the forest. A high gamma value causes training to prefer small trees. A small gamma value results in larger individual trees and slower training. By default, this value is calculated during hyperparameter optimization. It must be a nonnegative value.

            • eta number

              Advanced configuration option. The shrinkage applied to the weights. Smaller values result in larger forests which have a better generalization error. However, larger forests cause slower training. By default, this value is calculated during hyperparameter optimization. It must be a value between 0.001 and 1.

            • Advanced configuration option. Specifies the rate at which eta increases for each new tree that is added to the forest. For example, a rate of 1.05 increases eta by 5% for each extra tree. By default, this value is calculated during hyperparameter optimization. It must be between 0.5 and 2.

            • Advanced configuration option. Defines the fraction of features that will be used when selecting a random bag for each candidate split. By default, this value is calculated during hyperparameter optimization.

            • Advanced configuration option. Controls the fraction of data that is used to compute the derivatives of the loss function for tree training. A small value results in the use of a small fraction of the data. If this value is set to be less than 1, accuracy typically improves. However, too small a value may result in poor convergence for the ensemble and so require more trees. By default, this value is calculated during hyperparameter optimization. It must be greater than zero and less than or equal to 1.

            • If the algorithm fails to determine a non-trivial tree (more than a single leaf), this parameter determines how many of such consecutive failures are tolerated. Once the number of attempts exceeds the threshold, the forest training stops.

            • Advanced configuration option. A multiplier responsible for determining the maximum number of hyperparameter optimization steps in the Bayesian optimization procedure. The maximum number of steps is determined based on the number of undefined hyperparameters times the maximum optimization rounds per hyperparameter. By default, this value is calculated during hyperparameter optimization.

            • Advanced configuration option. Defines the maximum number of decision trees in the forest. The maximum value is 2000. By default, this value is calculated during hyperparameter optimization.

            • The maximum number of folds for the cross-validation procedure.

            • Determines the maximum number of splits for every feature that can occur in a decision tree when the tree is trained.

            • Advanced configuration option. Machine learning uses loss guided tree growing, which means that the decision trees grow where the regularized loss decreases most quickly. This soft limit combines with the soft_tree_depth_tolerance to penalize trees that exceed the specified depth; the regularized loss increases quickly beyond this depth. By default, this value is calculated during hyperparameter optimization. It must be greater than or equal to 0.

            • Advanced configuration option. This option controls how quickly the regularized loss increases when the tree depth exceeds soft_tree_depth_limit. By default, this value is calculated during hyperparameter optimization. It must be greater than or equal to 0.01.

            • The minimum outlier score that a document needs to have in order to calculate its feature influence score. Value range: 0-1

            • method string

              The method that outlier detection uses. Available methods are lof, ldof, distance_kth_nn, distance_knn, and ensemble. The default value is ensemble, which means that outlier detection uses an ensemble of different methods and normalises and combines their individual outlier scores to obtain the overall outlier score.

            • Defines the value for how many nearest neighbors each method of outlier detection uses to calculate its outlier score. When the value is not set, different values are used for different ensemble members. This default behavior helps improve the diversity in the ensemble; only override it if you are confident that the value you choose is appropriate for the data set.

            • The proportion of the data set that is assumed to be outlying prior to outlier detection. For example, 0.05 means it is assumed that 5% of values are real outliers and 95% are inliers.

            • If true, the following operation is performed on the columns before computing outlier scores: (x_i - mean(x_i)) / sd(x_i).

Open a point in time Added in 7.10.0

POST /{index}/_pit

A search request by default runs against the most recent visible data of the target indices, which is called point in time. Elasticsearch pit (point in time) is a lightweight view into the state of the data as it existed when initiated. In some cases, it’s preferred to perform multiple search requests using the same point in time. For example, if refreshes happen between search_after requests, then the results of those requests might not be consistent as changes happening between searches are only visible to the more recent point in time.

A point in time must be opened explicitly before being used in search requests.

A subsequent search request with the pit parameter must not specify index, routing, or preference values as these parameters are copied from the point in time.

Just like regular searches, you can use from and size to page through point in time search results, up to the first 10,000 hits. If you want to retrieve more hits, use PIT with search_after.

IMPORTANT: The open point in time request and each subsequent search request can return different identifiers; always use the most recently received ID for the next search request.

When a PIT that contains shard failures is used in a search request, the missing are always reported in the search response as a NoShardAvailableActionException exception. To get rid of these exceptions, a new PIT needs to be created so that shards missing from the previous PIT can be handled, assuming they become available in the meantime.

Keeping point in time alive

The keep_alive parameter, which is passed to a open point in time request and search request, extends the time to live of the corresponding point in time. The value does not need to be long enough to process all data — it just needs to be long enough for the next request.

Normally, the background merge process optimizes the index by merging together smaller segments to create new, bigger segments. Once the smaller segments are no longer needed they are deleted. However, open point-in-times prevent the old segments from being deleted since they are still in use.

TIP: Keeping older segments alive means that more disk space and file handles are needed. Ensure that you have configured your nodes to have ample free file handles.

Additionally, if a segment contains deleted or updated documents then the point in time must keep track of whether each document in the segment was live at the time of the initial search request. Ensure that your nodes have sufficient heap space if you have many open point-in-times on an index that is subject to ongoing deletes or updates. Note that a point-in-time doesn't prevent its associated indices from being deleted. You can check how many point-in-times (that is, search contexts) are open with the nodes stats API.

Path parameters

  • index string | array[string] Required

    A comma-separated list of index names to open point in time; use _all or empty string to perform the operation on all indices

Query parameters

  • keep_alive string Required

    Extend the length of time that the point in time persists.

  • If false, the request returns an error if it targets a missing or closed index.

  • The node or shard the operation should be performed on. By default, it is random.

  • routing string

    A custom value that is used to route operations to a specific shard.

  • expand_wildcards string | array[string]

    The type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. It supports comma-separated values, such as open,hidden. Valid values are: all, open, closed, hidden, none.

  • Indicates whether the point in time tolerates unavailable shards or shard failures when initially creating the PIT. If false, creating a point in time request when a shard is missing or unavailable will throw an exception. If true, the point in time will contain all the shards that are available at the time of the request.

  • Maximum number of concurrent shard requests that each sub-search request executes per node.

Create an API key Added in 6.7.0

POST /_security/api_key

Create an API key for access without requiring basic authentication.

IMPORTANT: If the credential that is used to authenticate this request is an API key, the derived API key cannot have any privileges. If you specify privileges, the API returns an error.

A successful request returns a JSON structure that contains the API key, its unique id, and its name. If applicable, it also returns expiration information for the API key in milliseconds.

NOTE: By default, API keys never expire. You can specify expiration information when you create the API keys.

The API keys are created by the Elasticsearch API key service, which is automatically enabled. To configure or turn off the API key service, refer to API key service setting documentation.

External documentation

Query parameters

  • refresh string

    If true (the default) then refresh the affected shards to make this operation visible to search, if wait_for then wait for a refresh to make this operation visible to search, if false then do nothing with refreshes.

    Values are true, false, or wait_for.

application/json

Body Required

  • A duration. Units can be nanos, micros, ms (milliseconds), s (seconds), m (minutes), h (hours) and d (days). Also accepts "0" without a unit and "-1" to indicate an unspecified value.

  • name string
  • An array of role descriptors for this API key. When it is not specified or it is an empty array, the API key will have a point in time snapshot of permissions of the authenticated user. If you supply role descriptors, the resultant permissions are an intersection of API keys permissions and the authenticated user's permissions thereby limiting the access scope for API keys. The structure of role descriptor is the same as the request for the create role API. For more details, refer to the create or update roles API.

    NOTE: Due to the way in which this permission intersection is calculated, it is not possible to create an API key that is a child of another API key, unless the derived key is created without any privileges. In this case, you must explicitly specify a role descriptor with no privileges. The derived API key can be used for authentication; it will not have authority to call Elasticsearch APIs.

Delegate PKI authentication Added in 7.4.0

POST /_security/delegate_pki

This API implements the exchange of an X509Certificate chain for an Elasticsearch access token. The certificate chain is validated, according to RFC 5280, by sequentially considering the trust configuration of every installed PKI realm that has delegation.enabled set to true. A successfully trusted client certificate is also subject to the validation of the subject distinguished name according to thw username_pattern of the respective realm.

This API is called by smart and trusted proxies, such as Kibana, which terminate the user's TLS session but still want to authenticate the user by using a PKI realm—-​as if the user connected directly to Elasticsearch.

IMPORTANT: The association between the subject public key in the target certificate and the corresponding private key is not validated. This is part of the TLS authentication process and it is delegated to the proxy that calls this API. The proxy is trusted to have performed the TLS authentication and this API translates that authentication into an Elasticsearch access token.

External documentation
application/json

Body Required

  • x509_certificate_chain array[string] Required

    The X509Certificate chain, which is represented as an ordered string array. Each string in the array is a base64-encoded (Section 4 of RFC4648 - not base64url-encoded) of the certificate's DER encoding.

    The first element is the target certificate that contains the subject distinguished name that is requesting access. This may be followed by additional certificates; each subsequent certificate is used to certify the previous one.

Get role mappings Added in 5.5.0

GET /_security/role_mapping/{name}

Role mappings define which roles are assigned to each user. The role mapping APIs are generally the preferred way to manage role mappings rather than using role mapping files. The get role mappings API cannot retrieve role mappings that are defined in role mapping files.

External documentation

Path parameters

  • name string | array[string] Required

    The distinct name that identifies the role mapping. The name is used solely as an identifier to facilitate interaction via the API; it does not affect the behavior of the mapping in any way. You can specify multiple mapping names as a comma-separated list. If you do not specify this parameter, the API returns information about all role mappings.

Check user profile privileges Added in 8.3.0

GET /_security/profile/_has_privileges

Determine whether the users associated with the specified user profile IDs have all the requested privileges.

NOTE: The user profile feature is designed only for use by Kibana and Elastic's Observability, Enterprise Search, and Elastic Security solutions. Individual users and external applications should not call this API directly. Elastic reserves the right to change or remove this feature in future releases without prior notice.

External documentation
application/json

Body Required

  • uids array[string] Required

    A list of profile IDs. The privileges are checked for associated users of the profiles.

  • privileges object Required
    Hide privileges attributes Show privileges attributes object
    • application array[object]
      Hide application attributes Show application attributes object
      • application string Required

        The name of the application.

      • privileges array[string] Required

        A list of the privileges that you want to check for the specified resources. It may be either application privilege names or the names of actions that are granted by those privileges

      • resources array[string] Required

        A list of resource names against which the privileges should be checked.

    • cluster array[string]

      A list of the cluster privileges that you want to check.

    • index array[object]
      Hide index attributes Show index attributes object
      • names string | array[string] Required
      • privileges array[string] Required

        A list of the privileges that you want to check for the specified indices.

      • This needs to be set to true (default is false) if using wildcards or regexps for patterns that cover restricted indices. Implicitly, restricted indices do not match index patterns because restricted indices usually have limited privileges and including them in pattern tests would render most such tests false. If restricted indices are explicitly included in the names list, privileges will be checked against them regardless of the value of allow_restricted_indices.

Create a snapshot Added in 0.0.0

PUT /_snapshot/{repository}/{snapshot}

Take a snapshot of a cluster or of data streams and indices.

External documentation

Path parameters

  • repository string Required

    Repository for the snapshot.

  • snapshot string Required

    Name of the snapshot. Must be unique in the repository.

Query parameters

  • Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

  • If true, the request returns a response when the snapshot is complete. If false, the request returns a response when the snapshot initializes.

application/json

Body

  • If true, the request ignores data streams and indices in indices that are missing or closed. If false, the request returns an error for any data stream or index that is missing or closed.

  • If true, the current cluster state is included in the snapshot. The cluster state includes persistent cluster settings, composable index templates, legacy index templates, ingest pipelines, and ILM policies. It also includes data stored in system indices, such as Watches and task records (configurable via feature_states).

  • indices string | array[string]
  • feature_states array[string]

    Feature states to include in the snapshot. Each feature state includes one or more system indices containing related data. You can view a list of eligible features using the get features API. If include_global_state is true, all current feature states are included by default. If include_global_state is false, no feature states are included by default.

  • metadata object
    Hide metadata attribute Show metadata attribute object
    • * object Additional properties
  • partial boolean

    If true, allows restoring a partial snapshot of indices with unavailable shards. Only shards that were successfully included in the snapshot will be restored. All missing shards will be recreated as empty. If false, the entire restore operation will fail if one or more indices included in the snapshot do not have all primary shards available.
