Yeah - SpanQuery's don't use the boosts from subspans - it just uses
the idf for the query terms and the span length I believe - and the
boost for the top level Query.
Is that the right way to go? I guess Doug seemed to think so? I
don't know. It is sort of a bug that lower boosts would be ignored
right? There is an issue for it somewhere.
It gets complicated quick to change it - all of a sudden you need
something like BooleanQuery ...
Not sure it needs BooleanQuery, but it does seem like it should take
into account the scores of the subclauses (regardless of
BoostingTermQuery). There is a spot in creating the SpanScorer where
it gets the value from the QueryWeight, but this QueryWeight does not
account for the subclauses QueryWeights.
