Description

The method WildcardTermEnum#difference() is declared final. I found it very useful to subclass WildcardTermEnum to implement different scoring for exact vs. partial matches. The change is rather trivial (attached) but I guess it could make life easier for a couple of users.

I attached two patches:

• one which contains the single change to make difference() non-final (WildcardTermEnum.patch)
• one which does also contain some minor cleanup of WildcardTermEnum. I removed unnecessary member initialization and made those final. ( WildcardTermEnum_cleanup.patch)

Thanks simon
