Description

When requesting for a facet using the facet API on a specific field that doesnt have results, the response arrives without any other facet.
for example:
you have the following fields under meta_i_example

"example":[
        "-1",33743,
        "0",33739,
        "-2",33499,
        "2",33451,
        "1",0]},

when filtering on attribute "1" which has 0 results, not other results recieved.

Request

q=*:*&json.facet={facetForamount: {type : terms, field : amount, excludeTags : "tagForamount", mincount : 1, limit : 20 }}&json.nl=map&indent=true&fq={!tag=tagForamount}(amount:1)&fq=content_type:PARENT&rows=0&wt=json

Response

{"response":{"numFound":0,"start":0,"maxScore":0.0,"docs":[]},"facets":{"count":0}}
