WordPress自定义搜索页面分页返回404

我做了很多研究，测试了很多推荐的代码，但仍然找不到正确的方法来实现它。分页链接不工作。它将我导航到404页（在/？s=ddd页上找不到任何内容）。在某些情况下，它是有效的，但无法理解为什么不适用于所有情况（WORKS )这是我正在使用的代码。奇怪的是，这段代码在其他网站上运行得很好（LINK ), 但在（link ) . Permalinks被设置为“/%category%/%postname%/”，但我已经用其他类型进行了测试。仍然没有结果。

global $wpdb;
global $wp_query;
// If you use a custom search form
// $keyword = sanitize_text_field( $_POST[\'keyword\'] );
// If you use default WordPress search form
$keyword = get_search_query();
$keyword_meta = \'%\'.like_escape( $keyword ) . \'%\';
$keyword_title = like_escape( $keyword ) . \'%\';
$post_title_ids = $wpdb->get_col( $wpdb->prepare( "SELECT {$wpdb->posts}.ID FROM {$wpdb->posts} 
        WHERE {$wpdb->posts}.post_title LIKE \'%s\'", $keyword_title ) );

// Search in all custom fields
$post_ids_meta = $wpdb->get_col( $wpdb->prepare( "SELECT {$wpdb->posts}.ID FROM {$wpdb->postmeta} 
    LEFT JOIN {$wpdb->posts} ON {$wpdb->posts}.ID = {$wpdb->postmeta}.post_id
        WHERE (meta_key = \'_key\' AND meta_value LIKE \'%s\') GROUP BY {$wpdb->posts}.ID", $keyword_meta ) );

$paged =(get_query_var(\'paged\')) ? get_query_var(\'paged\') : 1;
$post_ids = array_merge($post_title_ids,$post_ids_meta);
// Query arguments
$args = array(      
    \'post_status\' => \'publish\',
    \'paged\' => $paged,
    \'orderby\'=>\'post__in\',
    \'post__in\' => $post_ids
);

$query = new WP_Query ( $args );
//set_include_order($query, $post_ids);

$temp = $wp_query; 
  $wp_query = null; 
  $wp_query = $query;

if ($query->have_posts() ):
    while ($query->have_posts() ) : $query->the_post(); ?>
