Elasticsearch 填充 | ElasticSearch 教程

#Elasticsearch 填充
在本节中，我们将向Elasticsearch添加一些索引，映射和数据。此数据将用于本教程中解释的示例中。

##创建索引
`POST http://localhost:9200/schools`

###请求正文
它可以包含索引特定的设置，但是现在，它的默认设置为空。
###响应
`{"acknowledged": true}`

这意味着创建索引成功

##创建映射和添加数据
Elasticsearch将根据请求体中提供的数据自动创建映射，我们将使用其批量功能在此索引中添加多个JSON对象。
`POST http://localhost:9200/schools/_bulk`

###请求体
```json
{
   "index":{
      "_index":"schools", "_type":"school", "_id":"1"
   }
}
{
   "name":"Central School", "description":"CBSE Affiliation", "street":"Nagan",
   "city":"paprola", "state":"HP", "zip":"176115", "location":[31.8955385, 76.8380405],
   "fees":2000, "tags":["Senior Secondary", "beautiful campus"], "rating":"3.5"
}
{
   "index":{
      "_index":"schools", "_type":"school", "_id":"2"
   }
}
{
   "name":"Saint Paul School", "description":"ICSE 
   Afiliation", "street":"Dawarka", "city":"Delhi", "state":"Delhi", "zip":"110075",
   "location":[28.5733056, 77.0122136], "fees":5000,
   "tags":["Good Faculty", "Great Sports"], "rating":"4.5"
}
{
   "index":{"_index":"schools", "_type":"school", "_id":"3"}
}
{
   "name":"Crescent School", "description":"State Board Affiliation", "street":"Tonk Road", 
   "city":"Jaipur", "state":"RJ", "zip":"176114","location":[26.8535922, 75.7923988],
   "fees":2500, "tags":["Well equipped labs"], "rating":"4.5"
}
```

响应结果：
```json
{
   "took":328, "errors":false,"items":[
      {
         "index":{
            "_index":"schools", "_type":"school", "_id":"1", "_version":1, "_shards":{
               "total":2, "successful":1, "failed":0
            }, "status":201
         }
      },

{
         "index":{
            "_index":"schools", "_type":"school", "_id":"2", "_version":1, "_shards":{
               "total":2, "successful":1, "failed":0
            }, "status":201
         }
      },

{
         "index":{
            "_index":"schools", "_type":"school", "_id":"3", "_version":1, "_shards":{
               "total":2, "successful":1, "failed":0
            }, "status":201
         }
      }
   ]
}
```

##添加另一个索引
###创建索引
`POST http://localhost:9200/schools_gov`

###请求正文
它可以包含索引特定的设置，但现在它的默认设置为空。

###响应
`{"acknowledged": true} (This means index is created)`

##创建映射和添加数据
`POST http://localhost:9200/schools_gov/_bulk`

###请求正文
```json
{
   "index":{
      "_index":"schools_gov", "_type":"school", "_id":"1"
   }
}
{
   "name":"Model School", "description":"CBSE Affiliation", "street":"silk city",
   "city":"Hyderabad", "state":"AP", "zip":"500030", "location":[17.3903703, 78.4752129],
   "fees":200, "tags":["Senior Secondary", "beautiful campus"], "rating":"3"
}

   }
}
{
   "name":"Government School", "description":"State Board Affiliation",
   "street":"Hinjewadi", "city":"Pune", "state":"MH", "zip":"411057",
   "location": [18.599752, 73.6821995], "fees":500, "tags":["Great Sports"], "rating":"4"
}
```

###响应
```json
{
   "took":179, "errors":false, "items":[
      {
        "index":{
           "_index":"schools_gov", "_type":"school", "_id":"1", "_version":1, "_shards":{
              "total":2, "successful":1, "failed":0
            }, "status":201
         }
      },

{
         "index":{
            "_index":"schools_gov", "_type":"school", "_id":"2", "_version":1, "_shards":{
               "total":2, "successful":1, "failed":0

         }
      }
