> 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).
