A friend of mine wanted to find some lyrics and the lack of proper verbatim mode has made it impossible to know if he had the wrong lyrics or if the information is not there or if the search itself is failing.
If there are no matches whatsoever then tell me there's no matches. If there's partial matches tell me how close it is to my search terms. Like you might match all but one or two words and so on. These are the kind of useful features I'd expect on search.
The usefulness of AI, on my mind, might be more towards interpretation of the questions rather than generation of the answers.
If I were Google I'd try something like using genAI to rephrase the question to extract keywords and so on that can be used to enhance search. But then again, I think I put myself in a position of "how do we make search better and more accurate" and that's simply not the position Google finds themselves in.
