I found that the hard way (squatter complained about it), but shouldn't 
it be mentioned in 
https://www.cyrusimap.org/3.6/imap/developer/install-xapian.html (or 
whatever the current page is, btw, the search on cyrusimap.org doesn't 
appear to be working).

ditto.

Anyway, I'm trying xapian on a test server with debian bullseye, using 
cyrus-imapd from their repository (3.6.1-4+deb12u3) and, after 
constructing the index with squatter (again, I think that should be 
mentioned in the xapian page) and adding the option 
"search_fuzzy_always:1" to imapd.conf (another detail not mentioned in 
the above page), every search returned no results, probably because of 
the missing conversations db.

I'm now trying the ctl_conversationsdb command but:

1) in spite of using -v (and -v -v) it doesn't tell me anything
2) it segfaulted
3) I see that the (incomplete?) conversation db for my 9.8GB mailbox is 
4.1GB, is that normal?

root@vmail:~# ls -lh /var/lib/cyrus/user/l/luca.conversations
-rw------- 1 cyrus mail 4.1G Sep 26 09:06 
/var/lib/cyrus/user/l/luca.conversations
root@vmail:~# du -sh /var/spool/cyrus/mail/user/luca/
9.8G    /var/spool/cyrus/mail/user/luca/


4) if I then try "ctl_conversationsdb -d luca" I see "Failed to open 
conversations database /var/lib/cyrus/user/l/luca.conversations: System 
I/O error" and in the journal

DBERROR: DUMMY level != maxlevel: 
filename=</var/lib/cyrus/user/l/luca.conversations> level=<30> 
maxlevel=<20> syserror=<No such file or directory> func=<read_header>
skiplist: closed while still locked
DBERROR: DUMMY level != maxlevel: 
filename=</var/lib/cyrus/user/l/luca.conversations> level=<30> 
maxlevel=<20> syserror=<No such file or directory> func=<read_header>
skiplist: closed while still locked

currently I'm running ctl_conversationsdb for each user, hoping that it 
doesn't segfault.

Bye
