Then again, others could be supported as well, and it's not really a requirement that the search can't handle more flexible searches.. Anyway, that's what Dovecot currently has implemented, and I guess it doesn't do what you want it to do. But there is a partial solution for this:

I'm trying to test it with the 2.2.1 installation, but have a problem
doing so: after seemingly smooth compilation and installation, I get

May 10 14:15:18 host dovecot: imap: Error: Module is for different ABI version 2.2.1 (we have 2.2.ABIv0(2.2.1)): /usr/lib/dovecot/modules/lib20_icu_plugin.so
May 10 14:15:18 host dovecot: imap: Fatal: Couldn't load required plugins

Any idea?

Greetings,
