Search Y Combinator

Question: Why isn't this linked from hacker news, in the header or footer?<p>Why do we keep waiting for questions on "how do I search hacker news", to pounce and share this link?

<a href="http://www.google.com/search?q=site:ycombinator.com+%s" rel="nofollow">http://www.google.com/search?q=site:ycombinator.com+%s</a><p>replace %s with search terms.

Works. Thank you. Search plug-in in FF works fine too.
