Hi, [~jpountz] , implementation of SortedNumericDocValues#docValueCount() means
numbers of values indexed per doc, duplicated value was also participated in
counting.
Does SortedSetDocValues#docValueCount() has the same semantic (currently they
have the same javadoc description)？ Or maybe you means only calculate the
number of unique values(ord)?

> Theoretically SortedSetDocValues gives more options to codecs with regard to
> how SORTED_SET doc values could store ords. However in practice we currently
> always store counts. Maybe giving SORTED_SET doc values an API that is closer
> to the API of SORTED_NUMERIC doc values would be a better trade-off?
