This commit reorganizes the docs to make Java API docs looking more like the REST docs. Also, with 2.0.0, FilterBuilders don't exist anymore but only QueryBuilders. Also, all docs api move now to docs/java-api/docs dir as for REST doc. Remove removed queries/filters ----- * Remove Constant Score Query with filter * Remove Fuzzy Like This (Field) Query (flt and flt_field) * Remove FilterBuilders Move filters to queries ----- * Move And Filter to And Query * Move Bool Filter to Bool Query * Move Exists Filter to Exists Query * Move Geo Bounding Box Filter to Geo Bounding Box Query * Move Geo Distance Filter to Geo Distance Query * Move Geo Distance Range Filter to Geo Distance Range Query * Move Geo Polygon Filter to Geo Polygon Query * Move Geo Shape Filter to Geo Shape Query * Move Has Child Filter by Has Child Query * Move Has Parent Filter by Has Parent Query * Move Ids Filter by Ids Query * Move Limit Filter to Limit Query * Move MatchAll Filter to MatchAll Query * Move Missing Filter to Missing Query * Move Nested Filter to Nested Query * Move Not Filter to Not Query * Move Or Filter to Or Query * Move Range Filter to Range Query * Move Ids Filter to Ids Query * Move Term Filter to Term Query * Move Terms Filter to Terms Query * Move Type Filter to Type Query Add missing queries ----- * Add Common Terms Query * Add Filtered Query * Add Function Score Query * Add Geohash Cell Query * Add Regexp Query * Add Script Query * Add Simple Query String Query * Add Span Containing Query * Add Span Multi Term Query * Add Span Within Query Reorganize the documentation ----- * Organize by full text queries * Organize by term level queries * Organize by compound queries * Organize by joining queries * Organize by geo queries * Organize by specialized queries * Organize by span queries * Move Boosting Query * Move DisMax Query * Move Fuzzy Query * Move Indices Query * Move Match Query * Move Mlt Query * Move Multi Match Query * Move Prefix Query * Move Query String Query * Move Span First Query * Move Span Near Query * Move Span Not Query * Move Span Or Query * Move Span Term Query * Move Template Query * Move Wildcard Query Add some missing pages ---- * Add multi get API * Add indexed-scripts link Also closes #7826 Related to https://github.com/elastic/elasticsearch/pull/11477#issuecomment-114745934

== Count API
|
|
|
|
The count API allows one to easily execute a query and get the number of
|
|
matches for that query. It can be executed across one or more indices
|
|
and across one or more types. The query can be provided using the
|
|
{ref}/query-dsl.html[Query DSL].
|
|
|
|
[source,java]
|
|
--------------------------------------------------
|
|
import static org.elasticsearch.index.query.QueryBuilders.*;
|
|
|
|
CountResponse response = client.prepareCount("test")
|
|
.setQuery(termQuery("_type", "type1"))
|
|
.execute()
|
|
.actionGet();
|
|
--------------------------------------------------
|
|
|
|
For more information on the count operation, check out the REST
|
|
{ref}/search-count.html[count] docs.
|

|
|
=== Operation Threading
|
|
|
|
The count API allows one to set the threading model the operation will be
|
|
performed when the actual execution of the API is performed on the same
|
|
node (the API is executed on a shard that is allocated on the same
|
|
server).
|
|
|
|
There are three threading modes.The `NO_THREADS` mode means that the
|
|
count operation will be executed on the calling thread. The
|
|
`SINGLE_THREAD` mode means that the count operation will be executed on
|
|
a single different thread for all local shards. The `THREAD_PER_SHARD`
|
|
mode means that the count operation will be executed on a different
|
|
thread for each local shard.
|
|
|
|
The default mode is `SINGLE_THREAD`.
