In addition the syntax for the serch is wrong in Google. 
The www is added which should not be: 
 
array site:www.php.net 
 
The correct syntax in Google is: 
 
site:php.net array 
 
But this still provides a sitewide search... 
The old Google syntax allowed for sub-directories: 
 
site:php.net/manual array 
 
But now that will not work! 
It seems that the only way to solve this problem (which is 
really a Google problem...) is to create a subsite that 
Google can index. But we already have docs.php.net so we 
just need to changethe www. to docs. and problem is 
solved: 
 
site:docs.php.net array 
 
And it finds the page as the first one! 
But it's still not as good as the old search that 
imediately took me to the function if it existed. 
We should be able to use Google's lucky search to do this 
or we can implement it separate from google before the 
redirect in the search.php script...

The www is intentionally included, to not include the mirror sites in the search results. docs.php.net is damn slow, it is just a test server for our upcoming livedocs documentation renderer which will include manual restricted search, so please be (a bit) patient.

Our website only has a few pages more than the manuals, so I don't think this is a critical problem.
