Not really. The idea is to write the query in a file that is then passed
to the tool (notmuch, mu, anyelse), which looks into its index and then
return all the ID of the messages matching. I only get the 600 first
messages, in order to speed up the fetching and finally ask mutt to
display them in mutt.

The version I gave is a slight improvement of something I found
there (http://log.or.cz/?p=228). They may be other better way, but I
d'say this one is already fast enough.
