I would be surprised if Gnus did anything but appending _during
splitting_.

Depends. It can use several backends. Since the IMAP protocol
provides searching, nnir provides whatever IMAP provides. Which is
full-text regexp searches plus Boolean connectives, if I'm not
mistaken.
But for nnml, say, you can use a different search engine which might
provide other nifty things like `sounds similar' searches or stemming
or ranking. Or all of them, as is the case with freeWAIS-sf :-)
I hope that we will be able to integrate a real IR engine with the
Cyrus server, someday. That would really be KEWL!
