title: Django/Haystack error: elasticsearch.exceptions.RequestError: TransportError(400, 'parsing_exception',...)
body: <p>I am using elasticsearch as backend for haystack in my Django project. I created everything required for a search as mentioned <a href="http://krzysztofzuraw.com/blog/2016/haystack-elasticsearch-part-two.html" rel="noreferrer">here</a>. But when i search i throws a traceback error with TransportError(400, 'parsing_exception', 'no [query] registered for [filtered]'). </p>
  
  <p>I have googled for this issue. But don't get any solution. I would appreciate helping me solve this.</p>
  
  <p>My traceback:</p>
