== Query DSL
|
|
|
|
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
|
|
<<java-search,Search API>>.
|
|
|
|
To use `QueryBuilders` just import them in your class:
|
|
|
|
[source,java]
|
|
--------------------------------------------------
|
|
import static 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`.
