下载后进入bin目录启动服务
启动kibana时要保证已经将Elasticsearch服务启动，因为kibana是依赖于Elasticsearch
启动后输入[http://localhost:5601/](http://localhost:5601/)即可进入页面进行操作
点击页面上以下按钮即可进入编辑页面用来编辑Elasticsearch增删改查语句
删除某个index
```java
DELETE /blog
```
新增数据
```java
PUT /abc//创建index
//向index中添加数据
POST /abc/10
{
"first_name" : "John",
"last_name":"Smith",
"age":25,
"about":"I love go to rock climbing",
"interests":["sports","music"]
}
```
查询数据
```java
GET /person/_doc/1根据id
GET /person/_doc/_search?q=age:25根据age
POST /person/_search
{
"query":{
"bool": {
"should": [
{
"match": {
"last_name": "Smith"
}
}
]
}
}
}根据姓名等用post就需要这么写
第二种多个条件用should时代表的是or的意思
POST /person/_search
{
"query":{
"bool": {
"should": [
{
"match": {
"last_name": "Smith"
}
}
,
{
"match": {
"about": "rock"
}
}
]
}
}
}
第三种多个条件下用must代表and
POST /person/_search
{
"query":{
"bool": {
"must": [
{
"match": {
"last_name": "Smith"
}
}
,
{
"match": {
"about": "rock"
}
}
]
}
}
}
```
