I can think of two ways to get your hands on this information, simplest
one beeing you creating a filter with the documents that mached your
original query and then place new queries on the index with slop, non
slop, et c to find out whats what. This will of couse be very expensive
and is thus only an interesting solution for you if the response time is
good enough.
The second and cleaner solution is to create your custom Query(ies) or
hack the Weight of the queries you are currently using and have them
store this information when matching. A good implementation of this
would probably be a welcomed contribution to the project.
