ElasticSearch~ES索引操作~对索引的增删改查

一、创建索引 一、创建索引

PUT /student_test

二、创建索引并且指定分片数量(2个分片，2个副本)

PUT /student
{
  "settings": {
    "number_of_shards": 2,
    "number_of_replicas": 2
  }
}

三、创建索引并且指定分片数量与Mapping映射

PUT /teacher
{
  "settings": {
    "number_of_shards": 2,
    "number_of_replicas": 2
  },
  "mappings":{
    "properties":{
      "id":{
        "type":"integer"
      },
      "name":{
        "type":"keyword"
      },
      "age":{
        "type":"long"
      },
      "desc":{
        "type":"text"
      },
      "birthday":{
        "type":"date"
      }
    }
  }
}

二、查看索引 一、查看单个索引信息

GET /teacher

二、查看所有索引

GET /_cat/indices

三、查看指定索引文档总数

GET /student_test/_count

四、查看所有索引文档总数

GET _all/_count

五、查看单个索引切片信息

GET /_cat/shards/student_test?v

六、查看各索引占用内存大小并倒序

GET /_cat/indices?v&h=i,tm&s=tm:desc

七、查看个索引文档数量并倒序

GET /_cat/indices?v&s=docs.count:desc

八、查看健康状态为绿的索引

GET /_cat/indices?v&health=green

三、删除索引 一、删除单个索引

DELETE /student_test1

四、修改索引 一、修改分片副本

PUT /teacher/_settings
{
  "index":{
    "number_of_replicas":4
  }
}

二、新增Mapping映射

POST /teacher/_mapping
{
  "properties":{
    "phone":{
      "type":"keyword"
    }
  }
}
