elasticsearch query dsl queries

elasticsearch provides a full Java query dsl in a similar manner to the REST Query DSL. The factory for query builders is QueryBuilders. Once your query is ready, you can use the Search API.

See also how to build Filters

To use QueryBuilders just import them in your class:

import 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.

Match Query

See Match Query

QueryBuilder qb =QueryBuilders.matchQuery("name","kimchy elasticsearch");

MultiMatch Query

See MultiMatch Query

QueryBuilder qb =QueryBuilders.multiMatchQuery(
    "kimchy elasticsearch",     // Text you are looking for
    "user","message"           // Fields you query on
    );

Boolean Query

See Boolean Query

QueryBuilder qb =QueryBuilders
                    .boolQuery()
                    .must(termQuery("content","test1"))
                    .must(termQuery("content","test4"))
                    .mustNot(termQuery("content","test2"))
                    .should(termQuery("content","test3"));

Boosting Query

                .script("_score * doc['price'].value");         // Your script here

// If the script have parameters, use the same script and provide parameters to it.
QueryBuilders.customScoreQuery(QueryBuilders.matchAllQuery())
                .script("_score * doc['price'].value / pow(param1, param2)")

GeoShape Query

See GeoShape Query

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:

<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>
// 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;
// Shape within another
QueryBuilders.geoShapeQuery("location",
                newRectangleImpl(0,10,0,10,SpatialContext.GEO))
            .relation(ShapeRelation.WITHIN);

// Intersect shapes
QueryBuilders.geoShapeQuery("location",
                newPointImpl(0,0,SpatialContext.GEO))
            .relation(ShapeRelation.INTERSECTS);

// Using pre-indexed shapes
QueryBuilders.geoShapeQuery("location","New Zealand","countries")
            .relation(ShapeRelation.DISJOINT);
