Not that recently since I'm running Emacs 29.x but the manual says it is
deprecated since 28.x

In any case the manual doesn't mention any other search engines and if I
understand correctly nnir was the only one that supports imap search?

I think the manual should explain the background behind the system a bit
when it explains all the backends that can be used.
