fastadmin 是如何使用搜索功能的？
<form class="" action="{:addon_url('cms/search/index')}" method="get">
{:token('__searchtoken__')}
<div class="input-group">
<input class="form-control" name="q" data-suggestion-url="{:addon_url('cms/search/suggestion')}" type="search" value="{$Think.request.q|default=''|htmlentities}" placeholder="输入关键词进行搜索" style="height:39px;line-height: 39px;">
<span class="input-group-btn">
<button class="btn btn-primary ml-2" type="submit" style="border-radius:2px;padding:10px 30px;">搜索</button>
</span>
</div>
</form>
