This search feature is laughable. You can use it for anything even slightly salacious. I tried all sorts of taboo subjects to bring up something, but nada. It's way to limiting. It's essentially censoring the Internet. If they don't add an adult mode or safe search option then this will never come close to beating google

yes the censorship is unacceptable, but for subjects that aren't censured it gets reasonably good answer, quicker than having to look on multiple links
