I have a vague understanding of how Google search works, so I set my expectations accordingly. I probably don't want to get dumped into source code when looking up error messages, I want to find posts by other people who got the same error and see how they fixed it. I don't expect small businesses to have web sites or SEO or to do anything to promote their business online, so I'm not surprised when a local sawmill or barbershop or mom 'n' pop restaurant doesn't show up -- how would Google know about such places if they don't have web sites, reviews, incoming links? I have seen plenty of ads and SEO abuse and had to wade through W3Schools and TutorialPoint junk links looking up programming questions. I know how to focus my search on specific domains and how to exclude domains when I need to drill down. The examples you give seem like holes in Google's index that have probably always been that way, not a new shortcoming, though I don't know for sure because I haven't keept close track. I've started to use DDG more often because Google started using "AI" for search, and I have no interest in that, I usually know what I want to find and don't need LLMs auto-completing and hallucinating results for me.
