If a user doesn't have a userpage, there is no page to search for which is why you cannot search for them through the search bar.

The userpage creation depends on the welcome bot configuration for the wiki, the current phase of the moon and other weird things.

There is no way for you to see which wiki a user edits on Fandom without using an outside search engine.
