<form class="form-inline my-2 my-lg-0" role="search" method="get" action="/Search/SearchList" target="_blank">
<div class="input-group">
<input type="text" class="form-control" name="keyword" placeholder="全站检索">
<span class="input-group-btn">
<button type="submit" class="btn btn-secondary">搜索</button>
</span>
</div><!-- /input-group -->
</form>

</div>
<button class="btn my-2 my-sm-0" type="submit" style="background:none; margin-left:-3rem; color:#ff9d00;" ><i class="zi zi_search" ></i></button>
