Yes. IndexedCatalog (http://www.async.com.br/projects/IndexedCatalog/)
does precisely what you want, without depending on any Zope-specific
modules. I've been `granted' maintainer status of it, and we run a
number of customer applications that use it daily with rather largish
databases (> 100,000 objects in more than a few catalogs), so I can
stand by it's functionality and schema migration niceties. I can't
promise it won't chew up your hard drive, but it hasn't done that to any
of ours yet <wink>

Use CVS HEAD if you're willing, it has been very stable lately and all
the pseudo-dangerous stuff is being developed on branches.

Take care,
