Merhabalar

Wordpress sitemde arama yaparken Türkçe kelime aranınca sonuçlar çıkmıyor.Mesela örnek aranan kelime "karışık" kelimesi arama sonucu "kar%C4%B1%C5%9F%C4%B1k" gibi çıkıyor ve sonuç bulunamıyor.Konu hakkında yardımlarınızı bekliyorm.Sayfanın tam olarak kodlaması şu şekil;

<?php

$options = get_option('wptube2');
get_header();

if(isset($_GET['order']) && !empty($_GET['order']))
{
	$order = $_GET['order'];
	switch($order)
	{ 
		case 'date_old' :	$orderby = '&orderby=date&order=ASC';
			break;
		case 'liked' :	$orderby = '&l_sortby=post_likes&l_orderby=desc';
			break;
		case 'viewed' :	$orderby = '&v_sortby=views&v_orderby=desc';
			break;
		case 'commented' :	$orderby = '&orderby=comment_count';
				function comment_count_orderby( $orderby ) {
					return "comment_count DESC";
				}
				add_filter('posts_orderby', 'comment_count_orderby');
			break;
		default :	 $orderby = '&orderby=date';
			break;
	}
}
if ( get_option('permalink_structure') != '' ) {
	if(is_search()){
	$order_url = get_search_link().'?order=';
	}
} else { 
	if(is_search()){
	$order_url = get_search_link().'&order=';
	}
}
