Adriano Crestani commented on LUCENE-3343:
------------------------------------------

Hi, sorry, I really didn't have much time to work on this lately.

But that's true, we still need to figure out how to apply the patch against 3.x, there are
some extra work to do to make it work with 3.x. I remember I applied the patch and some junits
were failing.

The patch is already applied to 4.0.
