I have one mail account which whenever I try the search built into smartermail it always reports no results found.  I have re-indexed the account and still search on the mailbox isn't working.  Anyone have any ideas how to fix a broken search for one user's email account?

 

edit:
As a further update it seems to be happening to all mailboxes in smartermail for messages past a certain time.  Older messages can be searched but any message past Saturday and it won't show up.
