+== 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 <<search,Search API>>.
+
+See also how to build <<query-dsl-queries,Queries>>.
+
+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.
+
+
+[[and-filter]]
+=== And Filter
+
+See {ref}/query-dsl-and-filter.html[And Filter]

+    FilterBuilders.prefixFilter("name.second", "ba")
+    );
+--------------------------------------------------
+
+Note that you can cache the result using
+`AndFilterBuilder#cache(boolean)` method. See <<query-dsl-filters-caching>>.
