=== Request Body Search
|
|
|
|
Specifies search criteria as request body parameters.

GET /twitter/_search

`GET /<index>/_search

The search request can be executed with a search DSL, which includes the
|
|
<<query-dsl,Query DSL>>, within its body.

See the search API's <<search-search-api-request-body,request body parameters>>.

|
==== Fast check for any matching docs
|
|
|
|
NOTE: `terminate_after` is always applied **after** the `post_filter` and stops
|
|
the query as well as the aggregation executions when enough hits have been
|
|
collected on the shard. Though the doc count on aggregations may not reflect
|
|
the `hits.total` in the response since aggregations are applied **before** the
|
|
post filtering.
|
|
|
|
In case we only want to know if there are any documents matching a
|
|
specific query, we can set the `size` to `0` to indicate that we are not
|
|
interested in the search results. Also we can set `terminate_after` to `1`
|
|
to indicate that the query execution can be terminated whenever the first
|
|
matching document was found (per shard).
|
|
|
|
[source,console]
|
|
--------------------------------------------------
|
|
GET /_search?q=message:number&size=0&terminate_after=1
|
|
--------------------------------------------------
|
|
// TEST[setup:twitter]
|
|
|
|
|
|
The response will not contain any hits as the `size` was set to `0`. The
|
|
`hits.total` will be either equal to `0`, indicating that there were no
|
|
matching documents, or greater than `0` meaning that there were at least
|
|
as many documents matching the query when it was early terminated.
|
|
Also if the query was terminated early, the `terminated_early` flag will
|
|
be set to `true` in the response.

// TESTRESPONSE[s/"took": 3/"took": $body.took/]
|
|
|
|
|
|
The `took` time in the response contains the milliseconds that this request
|
|
took for processing, beginning quickly after the node received the query, up
|
|
until all search related work is done and before the above JSON is returned
|
|
to the client. This means it includes the time spent waiting in thread pools,
|
|
executing a distributed search across the whole cluster and gathering all the
|
|
results.
