Wider range of search results

Hello. Sometimes, I get kicked from a server but have nobody there added as a friend or sometimes they change their names when I'm banned, so i can't really ask for an invite like. Neither it is easy to scroll months when you want one specific message. Could we have more specific filtering including the search for links or people from PREVIOUS servers as a bot autoban is not easy to back up?
Basically, more searching options and precision.
