No, it doesn't. It's just vague. Considering that happens all the time here, this reply is unreasonably nasty, and I'm surprised it got upvoted so quickly, or even at all - I guess you're not the only one having a bad day. A minor admonition and a link to How do I compose an effective node title? would have sufficed.
