如何在搜索页面遍历出文章的属性Property的内容

            {search module=MOD_DIR id=$searchid total=$sototal order=$params.order catid=$catid page=1 pagesize=5 urlrule=$urlrule}
                <li>
                    <a href="{$t.url}"><img src="{dr_thumb($t.thumb)}" width="175" height="175" alt="{$t.title}"></a>
                    <a href="{$t.url}"><span>{$t.title}</span></a>
                    {loop $t.ceshi $i $t2}
                    <div class="attr">{$t2.name}：{$t2.value}</div>
                    {/loop}
                </li>
            {/search}

上面的写法没有出数据
