To add to the mentioned answer below, all queries / filters are provided  
through simple static factories either using the QueryBuilders or  
FilterBuilders classes. Check how to use it here:  
[Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/java-api/query-dsl.html). The  
search page has an example of how to use it when searching:
