> Solr has a FunctionRangeQuery. It is constant scoring and also a post-filter.  Lucene has a FunctionRangeQuery that I added years ago LUCENE-6919.  It is not constant scoring as it scores based on the wrapped ValueSource, although this is easily made the same as Solr's by wrapping in a ConstantScoreQuery.  And it uses Lucene's TwoPhaseIterator indirectly which is equivalent functionality to Solr's PostFilter.  Consequently we can remove Solr's implementation.  Additionally, ValueSourceRangeFilter is a piece of the puzzle that can be removed as Solr's FunctionQuery was a wrapper around this specifically.  FYI Once upon a time, Query and Filter were separate, then Filter was made to subclass Query and then Filter was relegated to Solr as tech debt.
