Jquery(Ajax) 调用 SharePoint 2013 Search Rest API 并使用Josn反回结果并简单显示：
SharePoint 2010 中使用的 search.asmxSOAPwebservice在SharePoint 2013中已经被标记为过期， 但为了和老版本的Solution兼容还是可以用的。
而替代search.asmx的技术为SharePoint 2013 Search Rest API:
http://blogs.msdn.com/b/nadeemis/archive/2012/08/24/sharepoint-2013-search-rest-api.aspx
主要用于三方系统需要集成SharePoint 的 Enterprise Search 功能：
|
query |
使用Get方式取得查询结果,URL长度有限制 |
|
|
postquery |
使用Post方式取得查询结果,可以克服URL长度有限制 |
|
|
suggest |
使用Get 方式取得search suggestion(搜索建议) |
本文将展示用Jquery(Ajax) 调用 SharePoint 2013 Search Rest API 并使用Josn反回结果并简单显示的代码：
