Mikhail Khludnev commented on LUCENE-7871:
------------------------------------------
[~jpountz] Sorry for flashing it back after two years. I've stumbled upon this
code while tinkering LUCENE-9328. Isn't it's worth for {{ToParentDocValues}} to
implement {{DocValuesIterator}} since it already has {{advanceExact()}} but it
via calling {{advance()}} on underneath DV-iter?
> false positive match BlockJoinSelector[SortedDV] when child value is absent
