is quite a pain in gnus. It would be really nice to have a feature (possibly
thru `G w' in the group buffer?) that searches thru all mails. glimpse is a
very fast search engine (http://glimpse.cs.arizona.edu/, there is also an
.rpm) that seems very good for this kind of task.
glimpse requires an index to search, so you index your mail regularily in a
cron job, for example
glimpseindex -o -H ~/Mail/ ~/Mail/
This tells glimpse to index ~/Mail and leave an index file (size in this case
about 7-9% of all files) in ~/Mail/.glimpse_*.
Searching the index is even easier, for example
glimpse -H ~/Mail/ 'web;server;account'
looks in the index file, that glimpse finds in ~/Mail/.glimpse_*) and returns
a list of matching mails in the form
/home/swa/Mail/bxx-users/14: An RWI web server account will be needed and is
availble free on request.
/home/swa/Mail/bxx-users/17: >An RWI web server account will be needed and is
availble free on request.
Wouldn't this be an extremely useful feature?
Stefan.

I wish I had something that did the right thing. But at least I have
something that sort of works for one group only. Consider it to be an
intermediate solution till we get something better.
Usage: set gnus-glimpse-program and gnus-glimpse-options, type "G G"
in an nnml group. Tell me about things that don't work as you expect.
