a lot of content is just no longer produced and exposed to the open web (think about how much content goes into tiktok, discord, etc and you will never get that into your search results)
I see this all the time when trying to find information about old computers. So many of the good vintage computing resources are locked in social services or mailing lists that the information never shows up in search engines.
It feels a lot like the days when information was balkanized between AOL, GEnie, CompuServe, American PeopleLink, Delphi, etc.
Search engines were supposed to fix that and make all the world's information discoverable. They didn't.
