manual lookup / search

Hi! On manual pages, if you insert "mysq" into the >lookup box<, http://www.php.net/manual-lookup.php?lang=en&function=mysq comes up. If you write in "mysq" to the >search box<: http://www.php.net/manual-lookup.php?pattern=mysq&lang=en_US comes up. This is because function list is the default search method, and it is the same as lookup. My questions: 1. Why the search box provides incorrect language code?? 2. Do we really need the lookup box, as it is the same as the search box by default, and the search box is site-wide useable? BTW manual-lookup.php handles both "function" and "pattern" parameters the same way... Goba
