Yes, I’m always friendly when people do their research first (so as to not waste my time with answering things they could have found out themselves) and don’t simply hijack some vaguely related topic for completely different issues.
Any of them, except for the Latin one. Of course, a location editor could add “Confoederatio Helvetica” as an alias, and then you would be able to search by it, too.
Can you find out? This is what I mean by doing your own research.
Well, there you have your answer. But actually, you will find it called “Schweiz” on the direct search result page and in fact everywhere the area is referenced, except in indexed search (because the search server doesn’t serve the necessary information for that). Assuming, of course, you have set the interface language to German.
