Description

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).
