it amounts to a TermIterator::skip_to() and a while() loop.  :)

I'm going on vacation the first week of September (yay!).  I've got a 
long flight to my destination.  I can take a stab at implementing 
something at least equivalent to the basic matching I've done in java, 
and then we can tweak it from there...

makes sense.  I'll keep my fingers crossed.

Another thing I'd like to see is range searching.  Date, number, and 
character ranges.  This could be done as another QueryParser thing 
(syntax like "1:5" or "1...5" maybe).  I haven't yet done this in my 
java-based parser but will likely be doing it soon.  What do you think 
about this?  I seem to remember reading/seeing that Omega does 
something special for date-range searches.
