chrome搜索结果没有工具按钮

根据使用工具比如按时间段查询的链接的特点，写个油猴脚本将就用。

例子：

搜索java链接：https://www.google.com/search?q=java&oq=java&aqs=chrome.0.69i59j0i271l3j69i61l3j69i65.200j0j9&sourceid=chrome&ie=UTF-8

按一年时间段搜索：https://www.google.com/search?q=java&oq=java&aqs=chrome.0.69i59j0i271l3j69i61l3j69i65.200j0j9&sourceid=chrome&ie=UTF-8&tbs=qdr:y

多了 &tbs=qdr:y 参数，页面也有些错误，调整下 css 就行了。
