I am using Gnus with dovecot as IMAP server. Server-side searching
(using the IMAP SEARCH method) works reasonably well, probably because
Dovecot performs some indexing of incoming mails. Dovecot can also do
full text search indexing via several different search engines, but I
have not tried this. I think the IMAP SEARCH method only works on a
single folder, but with Gnus I can mark several folders and perform a
single search across them.
