What I understand you to mean is: you ask Google to give you the most-advertised product and hope that it's what's best for you.
Not sure what you mean here. Google started with PageRank which is a decent, albeit gamable, ranking algorithm. They’ve never not been leaning heavy on ranking.
Mid 2010s, Google began supporting conversational (non keyword) searches. This is because a good number of queries are difficult to reduce to keywords. But it is an inherently harder problem. And at the same time, the open web enahittified itself, filling up with SEOed blogspam. And a lot of user generated content moved into walled gardens.
This has been deprecated a long time ago (10 years ?). It hurts (ad) sells.
Edit: oops, you used it in another comment on here.
Maybe it is two different products: index search and fuzzy search?
