elasticsearch的增删命令备忘记录

创建一个文档 index/create

index 如果id不存在创建新的文档，否则先删除现有的文档，再创建新的文档，版本会增加

PUT test/_doc/1
{"user":"mike","comment":"you known,for search"}

如果id已经存在，会失败

PUT test/_create/1
{"user":"mike1","comment":"you known,for search"}

系统会自动生成id

POST test/_doc
{"user":"mike2","comment":"you known,for search"}

更新一个文档 update

文档必须已经存在，更新只会对相应字段做增量修改

POST test/_update/1
{"doc":{"user":"mike4","comment":"you known,for search","test":"55"}}

删除一个文档 delete

DELETE test/_doc/1

查一个文档 get

GET test/_doc/1
