Question

根据文档（http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-date-format.html），应该可以使用Joda时间兼容的日期模式来解析日期。

我的数据包含以下日期：“2015-02-09 02：10：05,245”。

可以使用以下模式使用Joda时间解析这些：“yyyy-MM-dd HH：mm：ss，SSS”。

但是，当我告诉我的索引使用此模式来解析日期时，将数据加载到Elasticsearch会失败并显示以下错误：

在索引模板中，'mydate'的指定方式如下：

{
  "template": "te*",
  "mappings": {
    "_default_" : {
      "properties": {
        "mydate": {
          "index": "analyzed",
          "type": "date",
          "format": "yyyy-MM-dd HH:mm:ss,SSS"
        }
      }
    }
  }
}

应该这样做，对吧？

这适用于ES 1.4.4

PUT hilden1

PUT hilden1/type1/_mapping
{
  "properties": {
    "dt": {"type": "date", "format": "yyyy-MM-dd HH:mm:ss,SSS"}
  }
}

POST hilden1/type1
{
  "dt": "2015-02-09 02:10:05,245"
}

GET hilden1/type1/_search

Elasticsearch无法使用自定义格式解析日期
