Description

When requesting a new ValueSourceScorer (with getRangeScorer) from DocTermsIndexDocValues , the latter instantiates a new iterator on SortedDocValues regardless of the fact that the underlying field can actually be of a different type (e.g. a SortedSetDocValues processed through a SortedSetSelector).
