WARNING: Version 5.0 of Elasticsearch has passed its EOL date.
This documentation is no longer being maintained and may be removed. If you are running this version, we strongly advise you to upgrade. For the latest information, see the current release documentation.
Request Body Search
editRequest Body Search
editThe search request can be executed with a search DSL, which includes the Query DSL, within its body. Here is an example:
GET /twitter/tweet/_search { "query" : { "term" : { "user" : "kimchy" } } }
And here is a sample response:
{ "took": 1, "timed_out": false, "_shards":{ "total" : 1, "successful" : 1, "failed" : 0 }, "hits":{ "total" : 1, "max_score": 1.3862944, "hits" : [ { "_index" : "twitter", "_type" : "tweet", "_id" : "0", "_score": 1.3862944, "_source" : { "user" : "kimchy", "message": "trying out Elasticsearch", "date" : "2009-11-15T14:12:12", "likes" : 0 } } ] } }
Parameters
edit
|
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. |
|
To retrieve hits from a certain offset. Defaults to |
|
The number of hits to return. Defaults to |
|
The type of the search operation to perform. Can be
|
|
Set to |
|
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 |
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.
Fast check for any matching docs
editIn 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).
GET /_search?q=message:elasticsearch&size=0&terminate_after=1
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.
{ "took": 3, "timed_out": false, "terminated_early": true, "_shards": { "total": 1, "successful": 1, "failed": 0 }, "hits": { "total": 1, "max_score": 0.0, "hits": [] } }
