Class ElasticSearchQueryBuilderImpl

java.lang.Object

org.dashbuilder.dataprovider.backend.elasticsearch.rest.impl.ElasticSearchQueryBuilderImpl

All Implemented Interfaces:

ElasticSearchQueryBuilder<ElasticSearchQueryBuilderImpl>

public class ElasticSearchQueryBuilderImpl
extends Object
implements ElasticSearchQueryBuilder<ElasticSearchQueryBuilderImpl>

Default query builder implementation.

It tries to use Filters as much as possible, as they're faster than queries.

If the resulting query only contains filters, wrap them into a MATCH_ALL filtered query, as aggregations do not work with post-filters (just filters, no queries).
