This is a great point. I'll add that search engines are also unclear about what kind of output they give. As you point out, search engines accept both questions and key words as queries. Arguably you'd want completely different searches/answers for those. Moreover, search engines no longer just output web sites with the key words but also give an "AI overview" in an attempt to keep you on their site, which is contrary to what search engines have traditionally done. Previously search engines were something you pass through but they now try to position themselves as destinations instead. I'd argue that search engines should stick to just outputting relevant websites and let LLMs give you an overview. Both technologies are complimentary and fulfill different roles.
