# 创建索引 #

PUT store   //创建索引
    
    GET /store   //查看索引
    
    DELETE store   //删除索引

## 创建数据结构 ##

PUT /store/_mapping/products?pretty
    {
      "properties": {
        "price": {
          "type": "long"
        },

## 存储数据 ##

POST /store/products/_bulk
    { "index": { "_id": 1 }}
    { "price" : 10, "name" : "陕西省西安市莲湖","owner":{"name" :"陕西省西安市莲湖","age":30}}
    { "index": { "_id": 2 }}
    { "price" : 20, "name" : "陕西省榆林市本地" ,"owner":{"name" :"陕西省榆林市本地","age":50}}
    { "index": { "_id": 3 }}
    { "price" : 30, "name" : "陕西省咸阳市本地","owner":{"name" :"陕西省咸阳市本地","age":20} }
    { "index": { "_id": 4 }}
    { "price" : 40, "name" : "陕西省榆林市莲湖","owner":{"name" :"陕西省榆林市莲湖","age":10} }

## 模糊匹配 ##

GET /store/_search
    {
      "query": {
        "match_phrase": {
          "name": ".*榆林市本地.*"
        }
