Example: Enrich your data based on exact values

match enrich policies match enrich data to incoming documents based on an exact value, such as a email address or ID, using a term query.

The following example creates a match enrich policy that adds user name and contact information to incoming documents based on an email address. It then adds the match enrich policy to a processor in an ingest pipeline.

Use the create index API or index API to create a source index.

The following index API request creates a source index and indexes a new document to that index.

PUT /users/_doc/1?refresh=wait_for
{
  "email": "[email protected]",
  "first_name": "Mardy",
  "last_name": "Brown",
  "city": "New Orleans",
  "county": "Orleans",
  "state": "LA",
  "zip": 70116,
  "web": "mardy.asciidocsmith.com"
}

Use the put enrich policy API to create an enrich policy with the match policy type. This policy must include:

PUT /_enrich/policy/users-policy
{
  "match": {
    "indices": "users",
    "match_field": "email",
    "enrich_fields": ["first_name", "last_name", "city", "zip", "state"]
  }
}

Use the execute enrich policy API to create an enrich index for the policy.

POST /_enrich/policy/users-policy/_execute

Use the put pipeline API to create an ingest pipeline. In the pipeline, add an enrich processor that includes:

PUT /_ingest/pipeline/user_lookup
{
  "description" : "Enriching user details to messages",
  "processors" : [
    {
      "enrich" : {
        "policy_name": "users-policy",
        "field" : "email",
        "target_field": "user",
        "max_matches": "1"
      }
    }
  ]
}

Use the ingest pipeline to index a document. The incoming document should include the field specified in your enrich processor.

PUT /my-index-00001/_doc/my_id?pipeline=user_lookup
{
  "email": "[email protected]"
}

To verify the enrich processor matched and appended the appropriate field data, use the get API to view the indexed document.

GET /my-index-00001/_doc/my_id

The API returns the following response:

{
  "found": true,
  "_index": "my-index-00001",
  "_type": "_doc",
  "_id": "my_id",
  "_version": 1,
  "_seq_no": 55,
  "_primary_term": 1,
  "_source": {
    "user": {
      "email": "[email protected]",
      "first_name": "Mardy",
      "last_name": "Brown",
      "zip": 70116,
      "city": "New Orleans",
      "state": "LA"
    },
    "email": "[email protected]"
  }
}
