David Smiley resolved SOLR-14800.
---------------------------------
    Resolution: Won't Fix

After looking at this some more, I'm closing this as Won't-Fix.  The FILTER clause of a BooleanQuery scores as 0.  So, I think FilterQuery should score this way because I think its semantic meaning is as a filter (it's in its name!) whereas DocSet.makeQuery (formerly getTopFilter) is generic.  Leaving that at 1.0 enables it to be boosted to 0 if desired but a user can't go the other direction easily.

> I see some inconsistency in what some "constant scoring queries" return for a score.  Lucene's ConstantScoreQuery yields 1 but it can be boosted (e.g. multiplied by whatever).  SolrConstantScoreQuery (which wraps a Filter) does the same.  Filter itself (which was modified to BE a Query years ago) yields 0 (not boostable), and so if it's used as a Query (vs only used as a supplier of DocIdSet), it's always 0.  Nearly all ConstantScoreQuery usages use the provided boost (often indirectly via score() which is initialized to the boost), and do not hard-code 0.  I think we should standardize on this approach.
> Note: ToParentBlockJoinQuery (and Child equivalent) use 0 (by code inspection) but this seems to be an anomaly.
