既然我们在Elasticsearch中有数据了，可以检索。
在es中非常简单，执行一个http的get请求，给定地址参数:index,type,id.

GET /megacorp/employee/1

响应如下：
{
  "_index" :   "megacorp",
  "_type" :    "employee",
  "_id" :      "1",
  "_version" : 1,
  "found" :    true,
  "_source" :  {
      "first_name" :  "John",
      "last_name" :   "Smith",
      "age" :         25,
      "about" :       "I love to go rock climbing",
      "interests":  [ "sports", "music" ]
  }
}
