I discovered this post from Karl Wettin in May about SpanNearQuery scoring:
http://www.nabble.com/SpanNearQuery-scoring-td17425454.html#a17425454
Karl apparently had the same expectations I had about the usage model of
spans and boosts. I also found JIRA issue 533 (SpanQuery scoring: SpanWeight
I'm not fully following what you want. Can you explain a bit more?

Suppose I create a SpanNearQuery phrase with the terms long range missiles

the score computed by SpanNearQuery.SpanScorer is based on the sloppy

I may take a crack at this. Any more thoughts you may have on the
implementation are welcome, but I don't want to distract you too much.
