In some usecases this could be important especially where the power of
a span query is not required.
I think the power of a spanquery is required for payloads though - the term
query will not hit each position to do payload loading - there is no need for
termquery to enumerate positions. Right?

Nothing different, I'm just concerned about the performance as the
SpanQuerys take about twice as long as a term query.
I run a little benchmark and found BoostingTermQuery being 1.5 times
slower than TermQuery without any payloads in the index.

Maybe I miss something, if so please let me know.

Hi, I looked at TermScorer today in order implement a TermQuery to
utilize Payloads from the index.
I realized that this class is final in the current trunk. It's kind of
obvious that is is declared final for optimization purposes.
I wanna know if it is possible to make it non final in the next
release or later to use it in a PayloadTermQuery class.
I would like to reuse this code and do some additional cleanups like
remove the code redundancy in score() / score(HitCollector, int).
Thanks,
Simon
