Description:
------------
Steps to reproduce:
* Enter "array_sort" into the search box
* The first search result reads:
  array_sort() - PHP
  www.php.net/array_sort
* Click on that link
* laugh

It links to the search itself, again and again.

I know (or guess) no array_sort() function at all exists. If the url 
"www.php.net/array_sort" is provided as an alias to the search "array_sort" 
because of the common pitfall of people searching for "array_sort", then that 
result should be excluded from the search.

It is especially funny (and nonsensical) that the result is shown as being 
titled "array_sort()" (note the parenthesis).
