Robert Muir commented on LUCENE-6371:
-------------------------------------
{quote}
I've removed SpanSimilarity, in favour of passing a map of Terms to
TermContexts to the SpanWeight constructor. If this is null, then scoring isn't
required; if not, then SpanWeight builds a SimScorer and passes that to its
scorer.
{quote}
I still don't understand what the purpose here was/is. We already have a
parameter {{needsScores}} for Query.createWeight. Why must there be another way
to do the same thing? Even a null seems like duplication of what already exists.
