[Dovecot] question about fts_squat

[Wojciech Puchar]

just installed dovecot with fts_squat
config attached after message.

When i telnet to imap server and execute by hand
1 login user password
select foldername
search body "someword"

it works fine, and at blazing speed except first run (indexing).
i already indexed everything by doveadm index offline to prevent server 
overload if multiple users (after i tell them) will try fulltext search.

All great BUT it doesn't work in thunderbird. Just gives zero results.

i used tcpdump to check how thunderbird executes it and it uses

search undeleted body "someword"

tried manually and it DOES NOT WORK. always give empty results.

even search all body "someword" doesn't work.

while

search body "someword"


always work very well.

what's wrong?
