From the 1.4.0 version, documentation explains the following: Index creation date
从 1.4.0 版本开始，文档解释了以下内容： 索引创建日期
When an index is created, a timestamp is stored in the index metadata for the creation date. By default this it is automatically generated but it can also be specified using the creation_date parameter on the create index API
创建索引时，时间戳会存储在创建日期的索引元数据中。默认情况下，它是自动生成的，但也可以使用 create index API 上的 creation_date 参数指定
curl -XPUT localhost:9200/test -d '{
"creation_date" : 1407751337000
}'

Elasticsearch now automatically includes the creation date for an index, for example:
Elasticsearch 现在会自动包含索引的创建日期，例如：
If I create a new index (with no settings)
如果我创建一个新索引（没有设置）
curl -XPOST 'localhost:9200/aoeu'
{"acknowledged":true}
I can now 'get' the index to retrieve its metadata:
我现在可以“获取”索引以检索其元数据：
curl -XGET 'localhost:9200/aoeu'
{
"aoeu": {
"aliases": {},
"mappings": {},
"settings": {
"index": {
"creation_date": "1429308615170",
"number_of_replicas": "1",
"number_of_shards": "5",
"uuid": "C5sqwXClSFyd5uF3MSrVgg",
"version": {
"created": "1050199"
}
}
},
"warmers": {}
}
}
You can see the creation_datefield above.
你可以看到creation_date上面的字段。
