[[search-request-body]]
== Request Body Search

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

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

And here is a sample response:

[source,js]
--------------------------------------------------
{
    "_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"
                }
            }
        ]
    }
}
--------------------------------------------------

[float]
=== Parameters

[horizontal]
`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`.

`search_type`::

    The type of the search operation to perform. Can be
    `dfs_query_then_fetch`, `query_then_fetch`, or 'scan'.
    Defaults to `query_then_fetch`.
    See <<search-request-search-type,_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`::

    experimental[The API for this feature may change in the future]
    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.
