You didn't mention at the beginning that you were looking for 200% damage servers, not for actual "200% tickets" in the server naming.
That's actually another filter you're using there with "200% damage"
Not the actual "search name" option.
Remove this filter too, and type "200" or "200%" in the name field to search for.
If you have it as a actual filter in "rules" then it searches for servers with that setting, not actually 200% being in the server naming itself.
Maybe can't see it anymore as they changed the server settings, so it's not 200% damage anymore.
If you can't see the server in your recent ones anymore which recently had this settings, then it might went down or expired.
As i remember this happening to me with a friend's server that expired, it went out of recent ones and favorites.
