fts solr ignores new mailboxes until fts rescan

[Giorgio Paolucci]

Hello,
on my debian wheezy installation, I implemented fts plugin with solr as
indexing system.
I noticed that if a user creates a new folder, that folder it is ignored by
dovecot indexing until a doveadm fts rescan is performed for that user.
 From that time on everything works ok on that folder.

As a test I set fts_autoindex=yes and put in that folder a brand new mail
never indexed before. in my logs indexer-worker says it indexed 0 messages

Obviously this is a major issue as users often create new folders, but a
search always returns empty  results.

My system is a debian wheezy with dovecot packages from backports  dovecot
2.2.13-11~bpo70+1.

Am I missing something? Any clue would be appreciated.

Thank you all in advance.
