[wp-docs] Limiting search to Codex

[Lorelle VanFossen]

It was an experiment but it worked. I've been frustrated over the 
inclusion of the Yahoo search on Codex bringing me tons of unrelated to 
Codex results and having to thumb through tons of posts and stuff before 
I can get to a single Codex article. But I found a solution!

keyword keyword site:codex.wordpress.org

It limits the search from right inside the search box to only results 
within the Codex. It's a handful of stuff to type, but when I'm looking 
ONLY on the codex, this is slick.

Maybe there should be check boxes to limit the search to Forums, Codex, 
or All. Worth considering.
