Search engines most certainly have their own algorithms, but it's common for them to have functions like AND NOT and OR, unless they're extremely simple. And the more terms they're going to be searching, the more important it becomes to have those functions, in order to narrow your searches.
I understand I exaggerated a bit when I said 'every search engine' but the primary message I was getting across still makes sense. Actually, give me an example of a search engine that doesn't have these functions in some way.
