index problem with only 1 folder of 1 box

7 Oct 2014


      Hello,
First of all, sorry for my poor english level.
I pass to solr indexing.
All is OK, except for the inbox of one of the mailboxes. For this inbox
(other folders of the same mailbox have no problems), when i do text
search, there is always no response.
Others mailboxes have no problems.
If i do a : "doveadm -Dv fts rescan -u mybox@domain.tld", i can do one
and only one search with the correct response. It index the folder, take
a few seconds and give me the good answer.
If i redo the same search, it's extremly quick with no answers. It's
like a cache problem but i don't know where and why...
Logs are not very verbose...
Here is an example of command line search :
$ nc 127.0.0.1 143

By the way, i try to clean solr cache with an :
echo 1 > /proc/sys/vm/drop_caches
and a restart of the server, but there is always the same problem...
Does anyone have an idea to explore?
sincerly yours,
Guillaume
