Ability for space admins to search archived pages

I like the ability to archive pages which are old, but there does not seem to be a way to include them in search results if necessary.  I can include archived spaces in search results, but not archived pages.

The use case for this isn't uncommon.  If users report not being able to find some critical piece of information, I need to be able to determine if they couldn't find it because the only occurrence of that information was on a page that was archived for being mostly out of date or even just archived accidentally/unintentionally.  When a search term doesn't appear in search results, I don't want to have to tell another team "sorry, could you give us that info again? We lost it in Confluence" nor manually check every archived page.
