在java elasticsearch中存储日期时间

Question

我正在尝试存储正在创建的实体的日期时间。我用org.joda.time.DateTime.now()创建DateTime对象。但它被存储在elasticsearch作为

{"centuryOfEra":20,"yearOfEra":2016,"yearOfCentury":16,"weekyear":2016,"monthOfYear":5,"weekOfWeekyear":18,"hourOfDay":15,"minuteOfHour":25,"secondOfMinute":28,"millisOfSecond":431,"dayOfYear":128,"year":2016,"dayOfMonth":7,"dayOfWeek":6,"era":1,"millisOfDay":55528431,"secondOfDay":55528,"minuteOfDay":925,"chronology":{"zone":{"fixed":false,"uncachedZone":{"cachable":true,"fixed":false,"id":"America/Los_Angeles"} 

是有，以指定的对象的存储像May 07 2016 14:58:44格式的方法吗？如果我们将它存储为字符串，那么我们仍然可以获得执行范围查询的性能优势？
