Too often people fill dupes of bugs that were just recently resolved. I think it's because they use just the basic search (hopefully they at least try this search before filing new bug I hope) and not the ALL variant, so they don't see these recently resolved bugs. So maybe it could be possible to make the default search also somehow include bugs that were recently resolved?
That's a bit tough to have just the recently resolved ones, but I'll consider it. It might wait for bugzilla3.
*** Bug 337097 has been marked as a duplicate of this bug. ***
Not implemented in 10 years, and I seriously doubt it's gonna be doable with Bugzilla's search parameters.
So my bug will also remain unfixed ... I was just trying to help reducing the number of dups ...
