Well, Cyrus IMAP provides fast server-side body searches using indexes, but
you'd have to configure it properly to use that feature.  It is lightweight
on the server side after the initial indexing (yes, it can do incremental
and staggered indexing).  Maybe Dovecot also needs some configuration to
index mailboxes for fast searching?

wu-imapd is not something one should bring up on polite conversation.
