== 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 `QueryBuilders` or `FilterBuilders` just import them in your class:
|
||
|
||
[source,java]
|
||
--------------------------------------------------
|
||
import static org.elasticsearch.index.query.QueryBuilders.*;
|
||
import static 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

|
||
prefixFilter("name.second", "ba")); <1>
|
||
--------------------------------------------------
|
||
<1> filters
|
||
