I think people don't know HOW to use search engines well. It takes something of a knack. Like MMario says, the "knack" needed by various search engines is different. It's not something you're born knowing how to do.

If the first time you search, you get a bunch of garbage and none of it is helpful, knowing what words to add or delete from your search string to get what you really want is really a fairly advanced skill.

Like MM, I can't get a decent answer out of Jeeves, but I can usually find what I'm looking for fairly quickly on Google. Is this because I'm stupid? I would think my success on Google proves my inability to use Jeeves isn't a case of stupidity. It's a knack I haven't mastered. And some people don't master ANY of them, and give up in disgust, perhaps thinking something like, "I've tried those search engines. They're rubbish."
