title: Can not resolve method hasChildQuery by using spring-data-elasticsearch?
body: <pre><code>QueryBuilder query = hasChildQuery(Province.CHILD_TYPE, QueryBuilders.termQuery("name", name.toLowerCase()), ScoreMode.None);
      List&lt;Province&gt; parents = operations.queryForList(new NativeSearchQuery(query), Province.class);
      return false;
  </code></pre>
  
  <p>I am using spring-data-elasticsearch.
  I don't know what class to import by resolving this method "hasChildQuery"?
  Anyone has encounter this kind of problem? This is my first time using spring-data-elasticsearch.
