Why are there no archived topics in the search and lists of topics/posts in the user profile?

Users complain that the search does not work well and they can not find some of their old messages.

P.S.: I had to remove all the old topics from the archive for their participation in the search.

This is part of what archiving does, specifically. The content remains present in an archived state, but is not available for searching or interacting with (replying, editing, etc.).
