Query Dsl

elasticsearch provides a full Java query dsl in a similar manner to the REST Query DSL. The factory for query builders is QueryBuilders and the factory for filter builders is FilterBuilders. Here is an example:

import static org.elasticsearch.index.query.xcontent.FilterBuilders.*;
import static org.elasticsearch.index.query.xcontent.QueryBuilders.*;

QueryBuilder qb1 = termQuery("name", "kimchy");

QueryBuilder qb2 = boolQuery()
                    .must(termQuery("content", "test1"))
                    .must(termQuery("content", "test4"))
                    .mustNot(termQuery("content", "test2"))
                    .should(termQuery("content", "test3"));

QueryBuilder qb3 = filteredQuery(
            termQuery("name.first", "shay"),
            rangeFilter("age")
                .from(23)
                .to(54)
                .includeLower(true)
                .includeUpper(false)
            );

The QueryBuilder can then be used with any API that accepts a query, such as count and search.
