I noticed a search for one word produces (for instance) 100 results and a search for two words produces a 1000 results. It seems to be looking for one OR the other and no option to search for both both. Adding quotes around both also does nothing. This is basic search tooling, and it seems to be broken.
I found it to be completely impossible to search for, for instance: "ARKit" and "Safari"
Perhaps is there a better way to search? Any suggestions? Maybe a Google search for these terms also including "Developer forums" and "Apple"??
