== 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

See {ref}/query-dsl-and-filter.html[And Filter]


[source,java]
--------------------------------------------------
FilterBuilders.andFilter(
    FilterBuilders.rangeFilter("postDate").from("2010-03-01").to("2010-04-01"),
    FilterBuilders.prefixFilter("name.second", "ba")
    );
--------------------------------------------------

Note that you can cache the result using
`AndFilterBuilder#cache(boolean)` method. See <<query-dsl-filters-caching>>.


=== Bool Filter

See {ref}/query-dsl-bool-filter.html[Bool Filter]


[source,java]
--------------------------------------------------
FilterBuilders.boolFilter()
    .must(FilterBuilders.termFilter("tag", "wow"))
    .mustNot(FilterBuilders.rangeFilter("age").from("10").to("20"))
    .should(FilterBuilders.termFilter("tag", "sometag"))
    .should(FilterBuilders.termFilter("tag", "sometagtag"));
--------------------------------------------------

Note that you can cache the result using
`BoolFilterBuilder#cache(boolean)` method. See <<query-dsl-filters-caching>>.

=== Geo Shape Filter

See {ref}/query-dsl-geo-shape-filter.html[Geo Shape

Note: the `geo_shape` type uses `Spatial4J` and `JTS`, both of which are
optional dependencies. Consequently you must add `Spatial4J` and `JTS`
to your classpath in order to use this type:

[source,xml]
-----------------------------------------------
<dependency>
    <groupId>com.spatial4j</groupId>
    <artifactId>spatial4j</artifactId>
    <version>0.3</version>
</dependency>

<dependency>
    <groupId>com.vividsolutions</groupId>
    <artifactId>jts</artifactId>
    <version>1.12</version>
    <exclusions>
        <exclusion>
            <groupId>xerces</groupId>
            <artifactId>xercesImpl</artifactId>
        </exclusion>
    </exclusions>
</dependency>
-----------------------------------------------

[source,java]
--------------------------------------------------
// Import Spatial4J shapes
import com.spatial4j.core.context.SpatialContext;
import com.spatial4j.core.shape.Shape;
import com.spatial4j.core.shape.impl.RectangleImpl;

// Also import ShapeRelation
import org.elasticsearch.common.geo.ShapeRelation;
--------------------------------------------------

[source,java]
--------------------------------------------------
// Shape within another
filter = FilterBuilders.geoShapeFilter("location",
    new RectangleImpl(0,10,0,10,SpatialContext.GEO))
    .relation(ShapeRelation.WITHIN);

// Intersect shapes
filter = FilterBuilders.geoShapeFilter("location",
    new PointImpl(0, 0, SpatialContext.GEO))
    .relation(ShapeRelation.INTERSECTS);

=== Caching

By default, some filters are cached or not cached. You can have a fine
tuning control using `cache(boolean)` method when exists.  For example:

[source,java]
--------------------------------------------------
FilterBuilder filter = FilterBuilders.andFilter(
        FilterBuilders.rangeFilter("postDate").from("2010-03-01").to("2010-04-01"),
        FilterBuilders.prefixFilter("name.second", "ba")
        )
    .cache(true);
--------------------------------------------------
