Suppose I create a SpanNearQuery phrase with the terms "long range missiles" and some slop factor. Each term is actually a BoostingTermQuery. Currently, the score computed by SpanNearQuery.SpanScorer is based on the sloppy frequency of the terms and their weights (this is fine). But even though each term is actually a BoostingTermQuery, the BoostingTermScorer (and therefore 'processPayload') is never invoked for this type of query.
I was looking for a way to have SpanNearQuery (also SpanOrQuery, SpanFirstQuery) recognize that the terms in the phrase should boost the overall score based on the payloads assigned to them. Thus the score from the SpanNearQuery would be higher if : a) the terms have payloads that boost their scores b) the terms are positionally next to each other (minimal slop - as it works now) Does this make sense?
