Personally, I wrote my own model to Xapian.

Sounds interesting! Do you care to share your code, or briefly explain
what is needed to do range searching?
I've currently got a hybrid approach, where I call QueryParser to
create a bunch of different queries, and then combine them.
I would be happy to share the code, although it's not really
CPAN-ready quite yet. The short version is that implementing things
like Range searching and Regular Expressions requires manually walking
through the term list, and adding all the terms that match to the
query.
It's basically the same way that Xapian's default query parser handles
right side wildcarding. You jump to the point in the termlist to
begin, and go until you get past the second condition.
Just for kicks, I've attached the basic class here. It's taken from
part of a larger project, and it definitely has some bugs. If you
decide to improve it, I would love patches.
It's been very helpful for comparison - thanks.

Thanks!
