Elasticsearch 入门 - Modifying Your Data

index/update/delete 均有大概1秒的缓存时间

Indexing/Replacing Documents

curl -X PUT "localhost:9200/customer/_doc/1?pretty" -H 'Content-Type: application/json' -d'
{
  "name": "John Doe"
}
'

replace/reindex:

curl -X PUT "localhost:9200/customer/_doc/1?pretty" -H 'Content-Type: application/json' -d'
{
  "name": "Jane Doe"
}
'

Index a new document with and ID of 2:

curl -X PUT "localhost:9200/customer/_doc/2?pretty" -H 'Content-Type: application/json' -d'
{
  "name": "Jane Doe"
}
'

Index a document without an explicit ID:

curl -X POST "localhost:9200/customer/_doc?pretty" -H 'Content-Type: application/json' -d'
{
  "name": "Jane Doe"
}
'

Updating Documents

Elasticsearch 的更新操作并非原位更新数据,不管什么时候更新操作都是删除旧文档后再索引新的文档。
将ID为1的文档name字段更新为 "Jane Doe":

curl -X POST "localhost:9200/customer/_doc/1/_update?pretty" -H 'Content-Type: application/json' -d'
{
  "doc": { "name": "Jane Doe" }
}
'

将ID为1的文档name字段更新为 "Jane Doe"的同时添加一个age字段:

curl -X POST "localhost:9200/customer/_doc/1/_update?pretty" -H 'Content-Type: application/json' -d'
{
  "doc": { "name": "Jane Doe", "age": 20 }
}
'

更新操作能够执行简单的脚本,例如使用脚本将age加5:

curl -X POST "localhost:9200/customer/_doc/1/_update?pretty" -H 'Content-Type: application/json' -d'
{
  "script" : "ctx._source.age += 5"
}
'

其中 ctx._source 指向当前需要被更新的文档。

Deleting Documents

删除ID为2的文档:

curl -X DELETE "localhost:9200/customer/_doc/2?pretty"
