0 hits from FacetedSearch when not specifying doc_types

I’m trying something simple to see if I can get it working: (I’m on 5.1)

class DogSearch(FacetedSearch):
    fields = ['fleas']
    facets = {
        'fleas': TermsFacet(field='fleas'),
    }
    index = [settings.ASSOCIATIONS_INDEX_NAME]

rs = DogSearch()
response = rs.execute()

But I’m getting 0 hits when I know there are lots of results.

Here’s what it’s generating when I run it:

{"query": {"match_all": {}}, "aggs": {"_filter_fleas": {"filter": {"match_all": {}}, "aggs": {"fleas": {"terms": {"field": "fleas"}}}}}, "highlight": {"fields": {"fleas": {}}}}

{"took":3,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":0,"max_score":null,"hits":[]},"aggregations":{"_filter_fleas":{"doc_count":0,"fleas":{"doc_count_error_upper_bound":0,"sum_other_doc_count":0,"buckets":[]}}}}

Could something be going wrong in the query, or am I just using this wrong?

use None for doc_types then, I will change it to be the default

Oh okay, is there an alternative I can use to target all types without manually listing them?
