We would like to propose following improvement while searching a content in Archived space:

There should be an option to search the content only within the Archived spaces.

1. When you enter a search term, Confluence looks for content in all spaces. Under the Space Filter with Search archived spaces toggle switch on, the search is performed within both Archive and Active spaces. But there is no option to perform the search only under Archived space.
2. This is also applicable for Advanced search: In space filter.
3. Searching archive space name does not show any results whereas the search only works with active space name.
4. If the toggle is set to Search archived spaces, it should be possible to filter only archived spaces in the space filter section

It would be good to have an option that allows content to be searched only in archived space. This would help differentiate between active and archived space.
