I'm fairly certain that BTree folders, Squishdot, and Racks all
use the BTree module that comes with zope, each in their own way.
(Note that that module has some issues with DB activity on writes,
which I believe someone is eventually going to fix...)

I have not experiemented with partial match searches, although
I did build the site with that type of index.

The catalog indexed just a few pretty short text properties,
and searching is really done only one one (the longest) field.
