# Has Parent Query > More info about has parent query is in the [official elasticsearch docs][1] The has parent query accepts a query and a parent type. The query is executed in the parent document space, which is specified by the parent type. This filter returns child documents which associated parents have matched. ## Simple example ```JSON { "has_parent" : { "parent_type" : "blog", "query" : { "term" : { "tag" : "something" } } } } ``` In DSL: ```php $termQuery = new TermQuery('tag', 'something'); $hasParentQuery = new HasParentQuery('blog', $termQuery); $search = new Search(); $search->addQuery($hasParentQuery); $queryArray = $search->toArray(); ``` [1]: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-has-parent-query.html
