[[count]] == Count API deprecated[2.1.0, Use the `search` api instead and set `size` to `0`] 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`.
