title: DeletebyQuery replacement in NEST 2.0.4
body: <p>My earlier version of NEST used to support the following code for DeleteByQuery</p>
  
  <pre><code>ESClient.DeleteByQuery&lt;object&gt;(q =&gt; q.Query(q1 =&gt; q1.QueryString(qs =&gt; qs.Query("*"))));
  </code></pre>
  
  <p>Now, that the nugetPackage of NEST elastic version has changed to 2.0.4, I am unable to work using the existing code. Could anyone please let me know what could be replacement for it. My Elastic Search is version 1.5.1</p>
  
  <p>Thanks
