Not sure, but it sounds like you are interested in a higher level
Query, kind of like the BooleanQuery, but then part of it sounds like
it is per document, right? Is it that you want to deal with multiple
payloads in a document, or multiple BTQs in a bigger query?

I'm using BoostingTermQuery to boost the score of documents with terms
containing payloads (boost value > 1). I'd like to change the scoring
behavior such that if a query contains multiple BoostingTermQuery
terms
(either required or optional), documents containing more matching
terms with
payloads always score higher than documents with fewer terms with
payloads.
Currently, if one of the terms has a high IDF weight and contains a
boosting
payload but no payloads on other matching terms, it may score higher
than
docs with other matching terms with payloads and lower IDF.
I think what I need is a way to increase the weight of a matching
term in
BoostingSpanScorer.score() if 'payloadsSeen > 0', but I don't see
how to do
this. Any suggestions?
Thanks,
Peter
