That’s still a thing, although it seems they’re A/B testing its removal. I just opened a private tab (as I always do) and got a boring "More results" button, but I tried another browser (also with a private tab) and got the classic pagination.
Today:
* Any term that might be related to a commercial product? That product comes first and frequently only.
* Search for two terms? It will first give it's prefer result for each separately - usually commercial products (ha). And then might give them together.
* Quoted terms are often taken as vague suggestions. Negative sign is often useless, etc.
