Searching on message status = unread often never returns any results or returns entirely wrong results Reproducible: Always Steps to Reproduce: 1. Open the Find Message Dialog 2. Specifiy All sub folders for a account root folder 3. Specify Message Status = unread 4. Click Search Actual Results: Usually no results are returned regardless of how many msgs are unread Sometime the previous result of an older unrelated search is returned. Once this happens it is impossible to get a serach to return anything else without restarting akonadi. Expected Results: A list of currently unread message should be returned. Searching in general is so broken and unreliable its hard to report it. None of the features are reliable.
I experience this same problem with kmail 4.12.80.
This seems to be working in latest 4.13/Master now, results aren't a 100% accurate, but very close.
