The Query/Scorer APIs don't provide any mechanism for information like 
that to be conveyed back up the call chain -- mainly because it's more 
heavy weight then most people need.

If you have custom Query/Scorer implementations, you can keep track of 
whatever state you want when executing a QUery -- in fact the SpanQuery 
family of queries do keep track of exactly the type of info you seem to 
want, and after executing a query, you can ask it for the "Spans" of any 
matching document -- the down side is the a loss in performance of query 
execution (because it takes time/memory to keep track of all the matches)
