Date Formatedit

In JSON documents, dates are represented as strings. Elasticsearch uses a set of pre-configured format to recognize and convert those, but you can change the defaults by specifying the format option when defining a date type, or by specifying dynamic_date_formats in the root object mapping (which will be used unless explicitly overridden by a date type). There are built in formats supported, as well as complete custom one.

The parsing of dates uses Joda. The default date parsing used if no format is specified is ISODateTimeFormat.dateOptionalTimeParser.

An extension to the format allow to define several formats using || separator. This allows to define less strict formats that can be used, for example, the yyyy/MM/dd HH:mm:ss||yyyy/MM/dd format will parse both yyyy/MM/dd HH:mm:ss and yyyy/MM/dd. The first format will also act as the one that converts back from milliseconds to a string representation.

Date Mathedit

The date type supports using date math expression when using it in a query/filter (mainly makes sense in range query/filter).

The expression starts with an "anchor" date, which can be either now or a date string (in the applicable format) ending with ||. It can then follow by a math expression, supporting +, - and / (rounding). The units supported are y (year), M (month), w (week), h (hour), m (minute), and s (second).

Here are some samples: now+1h, now+1h+1m, now+1h/d, 2012-01-01||+1M/d.

Note, when doing range type searches, and the upper value is inclusive, the rounding will properly be rounded to the ceiling instead of flooring it.

To change this behavior, set "mapping.date.round_ceil": false.
