Exactly, but I consider adding fake search that could find you ANY article, including not existent ones

This is excellent, congrats!

FYI I manually created this page and some link markup looks malformed: https://halupedia.com/list-of-uninhabited-countries

Looks like some single quote escaping issue? I suspect the first link to be "Archduke Ferdinand VII's Bureau of Non-Demographic Surveys" and the apostrophe breaks the link.

All articles exist, some just haven't been discovered yet ;)

Yes, that would be the perfect touch. This is brilliant satire. We need more satire!
