前面几篇博客已经介绍了ElasticSearch、Kibana和中文分词器ik的安装，该偏主要介绍ElasticSearch使用Kibana实现基本的增删改查操作

在启动ElasticSearch和Kibana后，在浏览器中输入http://<服务器主机名或IP>:5601，点击开发工具

1.添加索引

PUT /lib/
    {
      "settings":{
          "index":{
            "number_of_shards": 3, 
            "number_of_replicas": 0
            }
          }
    }

"number\_of\_shards": 分片数  
"number\_of\_replicas": 被分数  
lib是创建的索引名

也可以使用默认配置

put test

执行结果：
    {
      "acknowledged": true,
      "shards_acknowledged": true,
      "index": "test"
    }

2.查看索引

GET /lib/_settings

执行结果
    {
      "lib": {
        "settings": {
          "index": {
            "creation_date": "1552284280559",
            "number_of_shards": "3",
            "number_of_replicas": "0",
            "uuid": "d_Ry-sPrSiCx-u2UOwQlOA",
            "version": {
              "created": "6020499"
            },
            "provided_name": "lib"
          }
        }
      }
    }

查看所有索引

GET _all/_settings

3.添加文档

put /lib/user/1
    {
      "first_name":"Jane", 
      "last_name":"Smith",
      "age":32,
      "about":"I like to collect rock albums",
      "interests":["music"]
    }

user为该文档的类型

1是该文档的id

也可不指定id，但需要使用post命令，id会自动生成

post /lib/user
    {
      "first_name":"zhou", 
      "last_name":"Lucky",
      "age":18,
      "about":"I like to collect rock albums",
      "interests":["music"]
    }

未指定id时的执行结果：
    {
      "_index": "lib",
      "_type": "user",
      "_id": "J3UJfGkBgIN7A13YK5hV",
      "_version": 1,
      "result": "created",
      "_shards": {
        "total": 1,
        "successful": 1,
        "failed": 0
      },
      "_seq_no": 3,
      "_primary_term": 4
    }

根据id查看

get /lib/user/1/_source
    执行结果：
    {
      "first_name": "Jane",
      "last_name": "Smith",
      "age": 20,
      "about": "I like to collect rock albums",
      "interests": [
        "music"
      ]
    }
    
    
    get /lib/user/J3UJfGkBgIN7A13YK5hV/_source
    执行结果：
    {
      "first_name": "zhou",
      "last_name": "Lucky",
      "age": 18,
      "about": "I like to collect rock albums",
      "interests": [
        "music"
      ]
    }

4.更新文档

1.直接覆盖
    PUT /lib/user/1
    {
        "first_name" :  "Jane",
        "last_name" :   "Smith",
        "age" :         36,
        "about" :       "I like to collect rock albums",
        "interests":  [ "music" ]
    }
    
    2.只更新需要更新的字段
    POST /lib/user/1/_update
    {
      "doc":{
          "age":33
          }
    }

5.删除一个文档

DELETE /lib/user/1
    执行结果：
    {
      "_index": "lib",
      "_type": "user",
      "_id": "1",
      "_version": 3,
      "result": "deleted",
      "_shards": {
        "total": 1,
        "successful": 1,
        "failed": 0
      },
      "_seq_no": 4,
      "_primary_term": 4
    }

6.条件删除文档

delete lib/user/_query
    {
      "query": {
        "match": { "first_name": "zhou"}
      }
    }

7.删除索引

delete test
    
    执行结果：
    {
      "acknowledged": true
    }
