As you probably know, the way to use search engines is with different domains and search 'dorks' and commands that work to your advantage.
Such as .edu, .info, .forum, .net, etc etc etc. Because most engines always give .com automatically.
A dork could be to eliminate amazon from a .com search which would be -Amazon -- ex: spartacas sandals -Amazon. This should eliminate the hundreds of amazon returns google gives you in the first ten pages.
I would say a vast amount of users do not know how to use a search engine effectively much at all. But then again, the billionaire techbros don't want people to understand what they're doing in the first place with their products.
