Yonik Seeley commented on SOLR-4647:
------------------------------------

It should be really easy to add docvalues based fields to
TestGroupingSearch.testRandomGrouping

> There are a few places where grouping uses FieldType.toObject(SchemaField.createField(String,
float)) to translate a String field value to an Object. The problem is that createField returns
null when the field is neither stored nor indexed, even if it has doc values.
> An option to fix it could be to use the ValueSource instead to resolve the Object value
(similarily to NumericFacets).
