What mailbox format are you using? I had sdbox in 1.x and had some 
problems with the indexes when moving to 2.x. Even removing them did not 
solve the problem. The solution was to run doveadm force-resync for all 
mailboxes of all users (luckily it's a private server with only a few 
mailboxes and it can easily be scripted) to regenerate the indexes.
