The perfect search engine would be powered by humans with a search engine. Google is fantastic but there is no human understanding of the needs and wants that can be conveyed through series of keywords.

For example when I type "best humidifiers" I want a suggestion that is ideally based on accurate anecdotes of people who've experienced a brand in a variety of context and edge cases.

What google gives me is a cnet article listing Top 10 in 20XX. This is why I add reddit to the end of the search query now.
