对于客户端，我需要按类别对搜索结果页面上的结果进行分组。在这种情况下，它不是帖子，而是pages 从具有Add Tags And Category To Page And Post Types 插件。

这是未编辑的搜索结果页面模板：

    <div id="content">

        <main id="main" class="m-all t-2of3 d-5of7 cf" role="main">
            <h1 class="archive-title"><span><?php _e( \'Search Results for:\', \'bonestheme\' ); ?></span> <?php echo esc_attr(get_search_query()); ?></h1>

            <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

                <article id="post-<?php the_ID(); ?>" <?php post_class(\'cf\'); ?> role="article">

                    <header class="entry-header article-header">

这里的问题是，列出的所有页面都有一个类别，而不仅仅是有一个类别的搜索结果。循环似乎缺少某种搜索查询参数。我想知道如何改进页面模板，使其按类别显示搜索结果。也许有一个比我上面发布的更简单的方法？

提前感谢！
