If you could have access to every document (email, word document, government cable, pdf, jpg, txt, etc.) in the world containing a specific keyword, what would that keyword be, and why?<p>I've had this discussion a few times with different circles of friends, and each group has come up with completely different suggestions. The only rule is that the keyword needs to be a reasonable suggestion, and not something intentionally-broad like "the", "a", "and" designed to just capture every possible document.
