[wp-docs] Go option in Search box

[Lorelle VanFossen]

I have just done several searches for Codex links within the new search 
on the Codex. Two of the searches forced me to click through 3 pages of 
results before I encountered my first Codex article result. One of those 
I had to go to page 4 to get the result. I also miss the "GO" feature 
which took me directly to the page I wanted by entering in the correct 
name.

I know the idea is to tie the two together, and I'm not sure how to 
handle the search feature, but when I'm on the forum, I want an answer, 
any answer, but when I'm on the Codex, I often want an answer from the 
Codex, not a post on the forum. Maybe we can weight Codex results on top 
of forum and other results? I don't know how this works, but I was 
really frustrated, even when I typed in the specific title that I wanted.
