索引管理——创建，查询，删除

创建最简单的索引

PUT twitter

查询索引

GET twitter

删除索引

DELETE twitter

 

创建最简单的索引，然后查看它有哪些内容

 1 {
 2   "twitter": {  #索引名称
 3     "aliases": {}, #别名
 4     "mappings": {}, #映射是空的
 5     "settings": {   #索引设置
 6       "index": {
 7         "creation_date": "1571121395859",
 8         "number_of_shards": "5",  #分片 默认5
 9         "number_of_replicas": "1", #备份 默认1
10         "uuid": "N3gNve1aRxWSsoboXfX9Cg",
11         "version": {
12           "created": "6040399"
13         },
14         "provided_name": "twitter"
15       }
16     }
17   }
18 }
