Can't get hits.total when using filter_path

I’m using filter_path to filter the response on my aggregations, but I’m also interested in knowing the total number of hits for the query. For that, I’m adding hits.total to the filter_path list parameter.

The result object looks as expected:

ipdb> dir(result)
['aggregations', 'hits']

However, when I try to access the field in the result object, a KeyError exception is raised:

ipdb> result.hits
*** KeyError: 'hits'

Although if I inspect the result object, I see the total is there:

ipdb> result.__dict__['_d_']['hits']
{'total': 207}

Is there a way I can access this path? Thanks!

@jzbahrai sure, you should add it to the search object params:

Search(
            using=ElasticSearch(...),
            index='my_index',
            doc_type='document',
        ).params(
            filter_path=['hits.total', 'aggregations.my_aggregation', 'aggregations.myagg2.doc_count'] 
        )

Hey where did you add the filter_path to the request body? This says to add it in https://github.com/elastic/elasticsearch-py/blob/fc251751302da1b43a7789a402b03d87492c1227/docs/api.rst, but I can’t do it to the dsl.Search object. Can you point me to where you would do it for the dsl? Thanks! @jminuscula
