Product selection only if some criteria are met

I just did a roundup of 4K video projectors. The search results came back with lots of 1080p projectors. I often get product suggestions way outside of the original task. For example, if I define my audience as “dads look for an 4K projector that is good for gaming and family viewing,” but also add Sony in Focus section, I shouldn’t then get Sony earbuds.

Perhaps “Keywords” already does this, but I don’t think so….
