Paging not working when use "query_string"

[montenegrodr]

Assuming my query is:

my_query = 'name:Dave'

The following script works fine. I got the 20th to 30th docs.

s = Search(....)
s = s.query('match', name='Dave')
r = s[20:30].execute()

But when I use query_string, the paging does not work. It returns always the top-10 results, no matter which slicing values I use.

s = Search(....)
s = s.query(Q('query_string', query='name:Dave'))  # tried without Q as well
r = s[20:30].execute()                             # this returns top-10 results

I've checked from/size params stored in s and they are well assigned (from=20, size=10). But it seems they are completely ignored when I use query_string.

Debugging bit more, I found that for the first request (not using query_string) the request body is:

{
  "query": {
    "match": {
      "name": "Dave"
    }
  },
  "from": 20,
  "size": 10
}

And for the second snippet, the body is:

{
  "query": {
    "query_string": {
      "query": {
        "query_string": {
          "query": "name:Dave"
        }
      }
    }
  },
  "from": 20,
  "size": 10
}

Apparently, the to_dict() function is duplicating the query_string statement. ES isn't handling this format...

I am having trouble replicating your issue:

>>> from elasticsearch_dsl import Search, Q
>>> s = Search()
>>> s = s.query(Q('query_string', query='name:Honza'))
>>> s.to_dict()
{'query': {'query_string': {'query': 'name:Honza'}}}

could you please specify what version of elasticsearch-dsl you are using? Thank you!

Thanks for your reply. The bug was on my side. Sorry.
