Same experience I have had. Swapping to scholar gets me relevant results that aren't filled with ai gibberish and backwater Hokum. Still have to be careful about study sizes and sigma values and applicability, but miles ahead for at least getting to that being my issue.

Putting scientific in the search criteria should redirect there then.

What’s the scientific term for rocks?

I still remember trying to find the space group for Copper Telluride. No amount of technical terms could help me there.
