新增文档

语法格式：

PUT /Index/Type/id
{
  "json数据"
}

Elasticsearch 会自动建立 Index 和 Type，不需要提前创建，而且 Elasticsearch 默认会对 Document 的每个 field 都建立倒排索引，让其可以被搜索。

PUT /store/product/1
{
  "name": "gaolujie yagao",
  "desc": "gaoxiao meibai",
  "price": 30,
  "producer": "gaolujie producer",
  "tags": [
    "meibai",
    "fangzhu"
  ]
}

PUT /store/product/2
{
  "name": "jiajieshi yagao",
  "desc": "youxiao fangzhu",
  "price": 25,
  "producer": "jiajieshi producer",
  "tags": [
    "fangzhu"
  ]
}

PUT /store/product/3
{
  "name": "zhonghua yagao",
  "desc": "caoben zhiwu",
  "price": 40,
  "producer": "zhonghua producer",
  "tags": [
    "qingxin"
  ]
}
