Description

regular facet returns "0",33739, but JSON Facet API returns all values and counts without "0".
see the example:

{
  "responseHeader":{
    "status":0,
    "QTime":9,
    "params":{
      "q":"*:*",
      "json.facet":"{\n\tfacetForMeta_i_interactionSentiment: {\t\t\ntype : terms, \n\t\tfield : Meta_i_interactionSentiment\n\t}\n}",
      "facet.field":"Meta_i_interactionSentiment",
      "indent":"true",
      "fq":["channel:TelcoDefaultChannel",
        "content_type:PARENT"],
      "rows":"0",
      "wt":"json",
      "facet":"true"}},
  "response":{"numFound":167857,"start":0,"maxScore":1.0,"docs":[]
  },
  "facet_counts":{
