In order to be more consistent with what they do, the query cache has been renamed to request cache and the filter cache has been renamed to query cache. A known issue is that package/logger names do no longer match settings names, please speak up if you think this is an issue. Here are the settings for which I kept backward compatibility. Note that they are a bit different from what was discussed on #11569 but putting `cache` before the name of what is cached has the benefit of making these settings consistent with the fielddata cache whose size is configured by `indices.fielddata.cache.size`: * index.cache.query.enable -> index.requests.cache.enable * indices.cache.query.size -> indices.requests.cache.size * indices.cache.filter.size -> indices.queries.cache.size Close #11569

== 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"
|
|
}
|
|
}
|
|
]
|
|
}
|
|
}
|
|
--------------------------------------------------

|
|
=== 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.
|
|
|
|
`query_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 `query_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.
