Have you heard of this?
I heard it mentioned on a TV show and I needed to check this out. The person that described it sounded like a character off a prime time action TV show “Hacker”. Lots of big words but not really in the right order or even the correct context. I have this same problem with a lot of TV shows and movies.
I don’t know how a crawler could predict anything based of the information collected from the internet. If that was the case I guess you could do the same with any other search engine.
