I tested this right now on the 3.0 branch, and I can confirm there's an issue of matches not being found. I don't have an answer why this is so, yet. I'm working on it.

AFAIK the squat search engine does not support fuzzy search.

I am sure in my testing this setting didn't resolve the slow

search, but i don't remember if this setting did nothing,

or  failed to find anything at all or what else happened

with this configuration.

If I recall correctly, Cyrus uses the configured search engine only for fuzzy search. Non-fuzzy search is matched using the Cyrus-builtin routines, which will be slow: for body search it has to examine every message for that mailbox.

If your client is sending something like:

    C: 6 search body "body"

then it won't use the squat/xapian index, unless you have search_fuzzy_always set.

Cheers,

Robert
