[[query-dsl-filters]] == Query DSL - Filters elasticsearch provides a full Java query dsl in a similar manner to the REST {ref}/query-dsl.html[Query DSL]. The factory for filter builders is `FilterBuilders`. Once your query is ready, you can use the <>. See also how to build <>. To use `FilterBuilders` just import them in your class: [source,java] -------------------------------------------------- import org.elasticsearch.index.query.FilterBuilders.*; -------------------------------------------------- Note that you can easily print (aka debug) JSON generated queries using `toString()` method on `FilterBuilder` object.
