title: Elasticsearch python API: Delete documents by query
body: <p>I see that the following API will do delete by query in Elasticsearch - <a href="http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/docs-delete-by-query.html" rel="nofollow">http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/docs-delete-by-query.html</a></p>
  
  <p>But I want to do the same with the elastic search bulk API, even though I could use bulk to upload docs using</p>
  
  <pre><code>es.bulk(body=json_batch)
  </code></pre>
  
  <p>I am not sure how to invoke delete by query using the python bulk API for Elastic search.</p>
