I wanted to do a little cleanup in Gaming, and set off to search old closed questions other than exact duplicates, which would be candidates for deletion.
I was unable to find a way to specifically search for that, as searching for
closed:1 doesn't let me exclude the duplicates which I don't want to delete.
The only option I had was to click on every result to see in the question what the close reason was.
Could we have an advanced search option, or a section in the mod tools, that would allow me to search all closed questions that are not duplicates?
