I find the following works quite well for searching the mailing lists:

   - download all the archives from
   - import them into Thunderbird
   - use Google Desktop Search, or thunderbird's search

On Linux I suppose you'd have to use an alternative to GDS like Beagle or something.

Google has never indexed all the mailing lists on properly.  I never 
found out why, although I believe John Peterson looked into it at one stage and 
concluded that it wasn't easy to fix.  Google does index the mirrors though
