Description

I'd like to write a multi-value-configured FieldType that can return a DocValue Field from its createFields(). Since DocValues holds a single value per document for a field, you can only have one. However FieldType.createFields() is invoked by the DocumentBuilder once per each value being indexed.

FYI the reason I'm asking for this is for a multi-valued spatial field to store its points in DocValues.
