How to search for issues resolved in the last week

I’m trying to gather weekly statistics using the search feature or any other relevant way.

I want to find new errors in the last week. Which I think I can do with age :

is:unresolved age:-1w

But how do I search for issues that were resolved in the last week? I can’t find any search tag for this. I can’t even find a resolved timestamp anywhere when viewing an individual issue.
