Description

SOLR-13890 introduced a post-filter implementation for docValuesTermsFilter in  TermsQParserPlugin. But now it supports only multi-valued docValues fields (i.e. SORTED_SET type DocValues)

It doesn't work for single-valued docValues fields (i.e. SORTED type DocValues), though it should.
