Queue for closed tickets

Question

I am trying to create a queue for Closed tickets. Since open tickets are queried by:

Resolution = Unresolved

I assumed that I could pull up closed tickets by using:

Resolution != Unresolved.

However, this does not pull up the Resolved tickets. I've confirmed that the Status of Resolved does equal Done. Why does the above query not work? I know I can change the query to look by Status instead of Resolution instead but I'm asking why this does not work.

Alternatively you could check for the statusCategory instead:

statusCategory = Done

If you're really looking to see if an issue is resolved by using the Resolution field, I would check to see if it is empty.  Unresolved issues would not have a value for Resolution.
