新增文檔

語法格式：

PUT /Index/Type/id
{
  "json數據"
}

Elasticsearch 會自動建立 Index 和 Type，不需要提前創建，而且 Elasticsearch 默認會對 Document 的每個 field 都建立倒排索引，讓其可以被搜索。

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"
  ]
}
