Interesting, how long does it take to do an incremental index
medium/full for you?  Setting XAPIAN_FLUSH_THRESHOLD after my
patch yesterday should help noticeably, especially if you're on
HDD.

Totally understandable, and yes, if you can fit the LKML repos
into RAM it should be usable enough for a single user.

"git grep" also has the advantage of being able to use regexps,
which isn't possible with Xapian at the moment.

Yes.  I don't think there's a good way to implement search for
NNTP on the server side...  IMAP has specs for implementing
search; but I don't know how much overlap there is with what
our web UI currently offers.
