Google search is almost useless for anything but the most basic queries now. Anything technical and it ignores half of the search terms like you said.
Google Search has been in decline since they came up with Google+ and removed the Plus Operator from Google Search at the same time (and replaced it with quotes that don't do the same thing). About 13-14 years ago.
I asked them to review their decision and it was a NO... and there are no other remedies.
