This is how you can search for 'Closed' jobs on the system:

Click the 'View All' option in the 'Jobbags' (or 'Projects') side menu to get to the jobs listing.
Click the black triangle next to the 'View All Jobs' heading to open the search options.
Select the 'Closed' option from the 'Status' menu.
Click Go.

If you're not seeing expected results it may be that the search filter isn't going back far enough so select a higher time-span from the 'Show' menu and click Goagain.
