Could you get what you need combining the BoostingTermQuery with a
SpanNearQuery to produce a score? Just guessing here..
At some point, I would like to see more Query classes around the
payload stuff, so please submit patches/feedback if and when you get
a solution

I'm looking at the new Payload api and would like to use it in the

position) and a payload is stored with the first term of each
phrase. I
would like to create a custom query class that extends PhraseQuery
and uses
its PhraseScorer to find matching documents. The custom query class
then
reads the payload from the first term of the matching query and
uses it to
produce a new score. However, I don't see how to get the payload
from the
PhraseScorer's TermPositions. Is this possible?
