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.
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 :(
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.
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?
