The solution is older non-AI tech. Google search can say "no good results found" because it returns actual data rather than creating anything new. If you want a hard answer about the presence or absence of something, AI isnt the correct tool.

Can, but doesn't.

I can't remember the last time google actually returned no results.

It does reply with no results, but only for very long queries. E.g. If you search for two concatenated GUIDs, you can easily see a no results page.

ah, i get no results pages often when i search for quoted error strings from many different sources. Thing is, I have a hard time believing that no one has actually talked about at least some of those errors :(

So there are no other possibilities for us other than using a system that can be gamed for substandard results? Are we sure about this?
