Django/Haystack error: elasticsearch.exceptions.RequestError: TransportError(400, 'parsing_exception',...)

Question

I am using elasticsearch as backend for haystack in my Django project. I created everything required for a search as mentioned here. But when i search i throws a traceback error with TransportError(400, 'parsing_exception', 'no [query] registered for [filtered]').

I have googled for this issue. But don't get any solution. I would appreciate helping me solve this.

My traceback:

Traceback (most recent call last):
  File "c:\python34\lib\site- packages\haystack\backends\elasticsearch_backend.py", line 524, in search

no [query] registered for [filtered]

From what I can see you are running ES 5.0 and you're sending a filtered query which has been deprecated in ES 2.x and removed in ES 5.x.

You need to replace it with a bool/filter query instead.

So if you had something like this:

{
  "query": {
    "filtered": {
      "filter": {}
    }
  }
}

Simply replace it with

{
  "query": {
    "bool": {
      "filter": {}
    }
  }
}
