Description:
------------
As the summary says, saving the search-input as a keyword-search for firefox and then using it does not work... you always get a "The autocompleting search feature is accessible via the form elements at the top right of php.net pages."

Reproduce code:
---------------
1. Use Firefox to go to php.net
2. Right click on the field after "search for".
3. Choose "Add a keyword for this search...".
4. Enter "phpf" (for example) as keyword and something other as the name.
5. Type "phpf print" into the location field of firefox and press enter.


Expected result:
----------------
now i expected http://de.php.net/manual/de/function.print.php to show,

Actual result:
--------------
but instead i got http://de.php.net/search.php (yup. post is missing!)

For other pages like dict.leo.org the keyword search works find...
