索引基本操作

索引格式

PUT /my_index
{
  	## settings 用来设置分片，副本等信息
    "settings": { ... any settings ... },
    ## 字段映射，类型，分词器等
		"mappings": {
        "properties": { ... any properties ... }
    }
}

查找系统中所有的索引

GET /_cat/indices?v

## 查看索引setting信息
GET my_index/_setting

## 查看索引mapping信息
GET my_index/_mapping

创建索引

## 未指定分片，副本以及字段和字段类型信息
## setting 分片和副本会按elasticsearch配置文件中的指定数目配置
## mapping 映射字段和类型为空
PUT my_index

## 指定setting信息
PUT my_index
{
	"settings":{
  	"number_of_shards":1,
  	"number_of_replicas":1
	}
}

## 指定mapping信息
PUT my_index
{
	"mapping":{
  	"properties":{
    	"id":{
      	"type":"integer"
    	},
    	"title":{
      	"type":"keyword"
    	},
			"description":{
      	"type":"text"
    	}
		}
	}
}


## 创建索引，并指定setting/mapping
PUT my_index
{
  "settings": {
    "number_of_replicas": 1,
    "number_of_shards": 1
  },
  "mappings": {
    "properties": {
      "id":{
        "type": "integer"
      },
      "title":{
        "type":"keyword"
      },
      "price":{
        "type": "double"
      },
      "created_time":{
        "type":"date"
      },
      "description":{
        "type": "text"
      }
    }
  }
}

修改索引

PUT /my_index/_settings
{
  "settings": {
    "number_of_replicas": 0
  }
}

打开/关闭索引

• 关闭索引 – 索引被关闭后，查询索引信息只能显示元数据信息（mapping，setting可以查看），不能进行读写操作（查询数据和插入数据）

## 关闭索引
POST /my_index/_close

## 查询索引
GET /_cat/indices?v
## 结果展示
