我有以下搜索。php页面（这只是问题表示所需的代码）。

为什么我的$total_results 返回找到的许多帖子，但当我循环时，虽然它总是打印出来No posts found ?

<?php

$paged = (get_query_var(\'paged\')) ? get_query_var(\'paged\') : 1;
$query_args = explode("&", $query_string);
$search_query = array(\'posts_per_page\' => 10, \'paged\' => $paged);

foreach($query_args as $key => $string) {
     $query_split = explode("=", $string);
     $search_query[$query_split[0]] = urldecode($query_split[1]);
} 
$search = new WP_Query($search_query);
$total_results = $search->found_posts; // this returns 50

?>


<?php if ($search->have_posts()) : ?>
<?php while ($search->have_posts()) : $search->the_post(); ?>
    loop  through posts
<?php else : ?>
     No posts found.
<?php endif; ?>
