elseticsearch的基本命令

一.创建索引且格式化json输出 加上？pretty 就是格式化输出

然后查看所有索引库

   curl -XGET http://localhost:9200/_cat/indices?v

 

添加数据

curl -H "Content-Type: application/json" -XPUT http://localhost:9200/indexwb2/product/p1?op_type=create -d '{
> "name":"mac",
> "price":20000,
> "description":"苹果笔记本",
> "attr":["computer","高端"]
> }'

 

 如果数据已经存在会报错

 

curl -H "Content-Type: application/json" -XPUT http://localhost:9200/indexwb2/product/p1/_create -d '{
> "name":"mac",
> "price":20000,
> "description":"苹果笔记本",
> "attr":["computer","高端"]
> }'

这样的方式跟上面一样，数据存在会报错

 

还有一种设置如果没有数据会自动帮助你创建索引库，

 

设置完成后就会阻止自动创建索引库

 

 

查看数据

curl -XGET http://localhost:9200/aaap/product/p1?pretty

 

 然后只查看source里的部分内容

 选择不查看那些内容

 

修改数据

curl -H "Content-Type: application/json" -XPOST http://localhost:9200/aaap/product/p1/_update?pretty -d '{"doc":
> {"name":"新mac",
> "price":2000,
> "description":"苹果笔记本",
> "attr":["computer","高端"]}
> }'

 

删除数据

curl -XDELETE http://localhost:9200/aaap/product/p2?pretty

 

删除索引库

 curl -XDELETE http://localhost:9200/aaap?pretty
