             Summary: Empty buckets when faceting with JSON API on EnumField or TrieIntField
                 Key: SOLR-7497
                 URL: https://issues.apache.org/jira/browse/SOLR-7497
             Project: Solr
          Issue Type: Bug
          Components: faceting
    Affects Versions: 5.1, 5.2
         Environment: OS X 10.10.3
$ java -version
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)
            Reporter: Alfonso Muñoz-Pomer Fuentes


When using the JSON API, faceting on an EnumField or TrieIntField returns an empty list of buckets.

Steps to reproduce:
1. Define an EnumField.
schema.xml:
<field name="kingdom" type="kingdomEnum" indexed="true" stored="true" required="true" /> 
<fieldType name="kingdomEnum" class="solr.EnumField" enumsConfig="enumsConfig.xml" enumName="kingdom"/> 

enumsConfig.xml:
<?xml version="1.0" ?>
<enumsConfig>
    <enum name="kingdom">
        <value>plants</value>
        <value>metazoa</value>
        <value>fungi</value>
    </enum>
</enumsConfig> 

2. Add documents to core.

3. Faceting over the EnumField returns an empty list of buckets:
$ curl http://localhost:8983/solr/myCore/query -d '
{
  query: "*:*",
  facet : {
    kingdom : {terms : kingdom}
  }
}'
{ ...
  "facets":{
    "count":17,
    "kingdom":{
      "buckets":[]}}}

The same issue happens with TrieIntField. Using old-style facets works, this only happens with the new JSON API.

I tested changing the field to a string and I get the expected results.
