Thread: Dovecot indexing issue

i have mail folder 36000 emails in stored in maildir format. when doing full body searches using email client, takes quite while basic searches in message bodies , assume index not being used. when telneting mail server, try search, connection quits on me after few minutes , before index created.

a2 examine inbox
* flags (\answered \flagged \deleted \seen \draft junk nonjunk $label1 $label5 $forwarded $label2 $label3 $label4)
* ok [permanentflags ()] read-only mailbox.
* 35941 exists
* 0 recent
* ok [unseen 35861] first unseen.
* ok [uidvalidity 1264287638] uids valid
* ok [uidnext 59985] predicted next uid
* ok [highestmodseq 16] highest
a2 ok [read-only] select completed.

connection closed foreign host.

i thought maybe continue running in background, doing again second time yields same thing. did few more times , etas went down, quits every single time before 50%:
