Request Body Search

edit

Request Body Search

edit

The search request can be executed with a search DSL, which includes the Query DSL, within its body. Here is an example:

$ curl -XGET 'http://localhost:9200/twitter/tweet/_search' -d '{
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}
'

And here is a sample response:

{
    "_shards":{
        "total" : 5,
        "successful" : 5,
        "failed" : 0
    },
    "hits":{
        "total" : 1,
        "hits" : [
            {
                "_index" : "twitter",
                "_type" : "tweet",
                "_id" : "1",
                "_source" : {
                    "user" : "kimchy",
                    "postDate" : "2009-11-15T14:12:12",
                    "message" : "trying out Elasticsearch"
                }
            }
        ]
    }
}

Parameters

edit

`timeout`	A search timeout, bounding the search request to be executed within the specified time value and bail with the hits accumulated up to that point when expired. Defaults to no timeout. See Time units.
`from`	The starting from index of the hits to return. Defaults to `0`.
`size`	The number of hits to return. Defaults to `10`. If you do not care about getting some hits back but only about the number of matches and/or aggregations, setting the value to `0` will help performance.
`search_type`	The type of the search operation to perform. Can be `dfs_query_then_fetch` or `query_then_fetch`. Defaults to `query_then_fetch`. See Search Type for more.
`request_cache`	Set to `true` or `false` to enable or disable the caching of search results for requests where `size` is 0, ie aggregations and suggestions (no top hits returned). See Shard request cache.
`terminate_after`	The maximum number of documents to collect for each shard, upon reaching which the query execution will terminate early. If set, the response will have a boolean field `terminated_early` to indicate whether the query execution has actually terminated_early. Defaults to no terminate_after.

Out of the above, the search_type and the request_cache must be passed as query-string parameters. The rest of the search request should be passed within the body itself. The body content can also be passed as a REST parameter named source.

Both HTTP GET and HTTP POST can be used to execute search with body. Since not all clients support GET with body, POST is allowed as well.
