[[query-dsl-queries]] == Query DSL - Queries elasticsearch provides a full Java query dsl in a similar manner to the REST {ref}/query-dsl.html[Query DSL]. The factory for query builders is `QueryBuilders`. Once your query is ready, you can use the <>. See also how to build <> To use `QueryBuilders` just import them in your class: [source,java] -------------------------------------------------- import org.elasticsearch.index.query.QueryBuilders.*; -------------------------------------------------- Note that you can easily print (aka debug) JSON generated queries using `toString()` method on `QueryBuilder` object. The `QueryBuilder` can then be used with any API that accepts a query, such as `count` and `search`.
