By 2020 or so it had been displaced by video walkthroughs on YouTube and today I would not expect a new game to have a good walkthrough (almost bought Visions of Mana on sale last weekend, turns out it has a text walkthrough but it isn't comprehensive like the old ones.)
Generally I don't like video walkthroughs, I mean who wants to scroll to the right point in 40 hours worth of videos for a 40 hour game? (There was one case in Megadimension Neptunia VII where I just couldn't figure out how to get through a certain world, turned out there was a place where it was possible to make a jump but it wasn't obvious to me that it was possible and the video made it clear.)
Now when I do find the time to play games I feel like I'm always beelining between any two given points, not stopping to take in the sights or enjoy the atmosphere, worrying about doing things "right"." It's definitely diminished my enjoyment of video games. If I could I'd find a way to trick myself into viewing games the same way I did back then regardless of the fact that I'm not putting in anywhere near as much, or as frequent, amounts of time into a savefile.
I don't know if you're making the point that a search at the time would have been a better or worse experience. Either way it shows that internet search has come at a cost. I don't know if it's actually best for us to further optimize and streamline it.
