ElasticSearch Date 类型

Date datatype

多种时间格式

Multiple date formats

Multiple formats can be specified by separating them with || as a separator. Each format will be tried in turn until a matching format is found. The first format will be used to convert the milliseconds-since-the-epoch value back into a string.
