我的搜索页面URL：

https://www.example.com/search/keyword/page/2/

这里是我的自定义搜索页面：

<?php 

    if($_GET[\'search_text\'] && !empty($_GET[\'search_text\']))

        $text = $_GET[\'search_text\'];
    }
    else
    {
        $text = urldecode( get_query_var(\'search_text\') ) ;            
    }

?>

我的分页链接创建得很好，但我总是看到第一页，因为不知何故query_vars[\'paged\'] 是emtpy。

我看到了Preserving Search Page Results and Pagination 上的节this page , 但我不知道该如何使用它，但我认为在我的情况下真的不需要这样做。

EDIT 1 (Response to comment from J.D.):

您提到的那个函数只返回一个产品ID数组，为了简化代码，我删除了我的函数，改为添加一个静态数组。

function wpse276396_search_filter($query) {
  if ( !is_admin() && $query->is_main_query() ) {
    if ($query->is_search) {
      $text = urldecode( get_query_var(\'search_text\') );
      $my_products = aws_search_byozan($text);
      $query->set(\'post_type\', \'product\');
      $query->set(\'posts_per_page\', 2);
      $query->set(\'post__in\', $my_products);
    }
  }
}
