Timo, many thanx for this! Finally I installed dovecot 1.2.9 from debian backports. Your fix have solved the problem. But look, it happens both for English and Russian emails: 1) I have testing mailbox with ~27000 emails. Big and small, 13Gb total. 2) Search (squat) for single word "planet" runs for 2-4 seconds. 3) Search for another word "Earth" runs fast as well. 4) Search for "planet Earth" runs for more than 3 minutes! And it uses a lot of I/O - server's HDD LED constantly blinks during the search.
I use horde/imp mail client. I can't believe the problem is squat internal design. There must be something wrong in algorithm implementation. With Thunderbird/Win32 there is same search delay. More, thunderbird can't search for Russian words - always no results. There are things to stabilize. I must say that squat is my preferable FTS engine, as you know SOLR engine has issues. I am very interested in easy and powerful IMAP search and would like to help you make it even better, as tester. Anyway, thank you for great product! -----Original Message----- From: dovecot-bounces+vuser1=test123...@dovecot.org [mailto:dovecot-bounces+vuser1=test123...@dovecot.org] On Behalf Of Timo Sirainen Sent: Tuesday, November 24, 2009 12:52 AM To: vus...@test123.ru Cc: dovecot@dovecot.org Subject: Re: [Dovecot] fts squat non-english search for 2 words On Wed, 2009-11-18 at 00:53 +0700, vus...@test123.ru wrote: > It looks I encoutered a bug or misconfiguration. fts_squat search for subject > and body works excellent for English mails.
