Is fts_autoindex_exclude options working fine?

[Alessio Cecchi]

Hi,

we have some trouble with Solr ad FTS engine. Solr have some spike of 
load and responding slow when an user expunge or append a message. 
fts_autoindex is set to "yes".

So I add to 90-plugin.conf these options:

fts_autoindex_exclude = Drafts
fts_autoindex_exclude2 = Spam
fts_autoindex_exclude3 = Trash
fts_autoindex_exclude4 = Sent

or

fts_autoindex_exclude = \Drafts
fts_autoindex_exclude2 = \Junk
fts_autoindex_exclude3 = \Trash
fts_autoindex_exclude4 = \Sent

But the problem is still present.

Here some example of logs when users have timeout in their email client, 
specially when saving in Drafts automatically:

Mar  7 12:21:37 pop01 dovecot: imap(user1 at company1.com) 
session=<flNVCZ/ZcO5dPnGT>: Warning: Maildir 
/home/vmail/domains/company1.com/user1/Maildir/.Drafts: Synchronization 
took 119 seconds (0 new msgs, 0 flag change attempts, 1 expunge attempts)

deleted=0 expunged=0 autoexpunged=1 trashed=0 appended=0 hdr_count=0 
hdr_bytes=0 body_count=0 body_bytes=0

Is my fts_autoindex_exclude wrong or there are some limits with this option?

Here the relevant part of 15-mailboxes.conf

namespace inbox {
   inbox = yes
   location =
   mailbox Archive {
     auto = subscribe
     special_use = \Archive
   }
   mailbox Drafts {
     auto = subscribe
     special_use = \Drafts
   }
   mailbox Sent {
     auto = subscribe
     special_use = \Sent
   }
   mailbox "Sent Messages" {
     special_use = \Sent
   }
   mailbox Spam {
     auto = subscribe
     special_use = \Junk
   }
   mailbox Trash {
     auto = subscribe
     special_use = \Trash
   }
   mailbox virtual/All {
     comment = All my messages
     special_use = \All
   }
   prefix =
   separator = /
}

Thanks
