# Has child Query > More info about has child query is in the [official elasticsearch docs][1] The has child query accepts a query and the child type to run against, and results in parent documents that have child docs matching the query. ## Simple example ```JSON { "has_child" : { "type" : "blog_tag", "query" : { "term" : { "tag" : "something" } } } } ``` In DSL: ```php $termQuery = new TermQuery('tag', 'something'); $hasChildQuery = new HasChildQuery('blog_tag', $termQuery); $search = new Search(); $search->addQuery($hasChildQuery); $queryArray = $search->toArray(); ``` [1]: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-has-child-query.html
