 #### 项目组件
 
 - 后台框架：[phalcon 3.4.5](https://phalcon.io)
 - 前端框架：[layui 2.5.6](https://layui.com)， [layim 3.9.5](https://www.layui.com/layim)（已授权）
+- 全文检索：[xunsearch 1.4.9](http://www.xunsearch.com)

 - 其它依赖：[php7.3](https://php.net)， [mysql5.7](https://mysql.com)， [redis5.0](https://redis.io)
 
 #### 使用协议
 
-虽然尝试了解开源协议，但是似乎不得要领，干脆用自己的协议吧，算不算开源我也不很清楚。

 1. 本系统属于强业务类型，非通用类库框架，不适合再次衍生发布。
 2. 在保留我们版权标识的前提下，用户可以修改以满足自己的需求，可以用于商业用途。
 3. 有限社区支持，用户对自己的行为负责。

 #### 会推出商业服务吗？
 
 - 如果不符合您对“开源”的认知，请移步其它同类产品，毕竟同类“免费”产品也很多。
-- 如果“开源”版本不能满足您的需求，或者您更希望有更好的支持，商业服务是不错的选择。
