-------------------------------------

[~dsmiley] Are you still planning to get that change into 4.x ?

It would allow us to solve a lot of problems that are way too hard to implement without the DateRangeField.

> LUCENE-5648 introduced a date range index & search capability in the spatial module. This issue is for a corresponding Solr FieldType to be named "DateRangeField". LUCENE-5648 includes a parseCalendar(String) method that parses a superset of Solr's strict date format.  It also parses partial dates (e.g.: 2014-10  has month specificity), and the trailing 'Z' is optional, and a leading +/- may be present (minus indicates BC era), and "*" means all-time.  The proposed field type would use it to parse a string and also both ends of a range query, but furthermore it will also allow an arbitrary range query of the form {{<calspec> TO <calspec>}} such as:
> {noformat}2000 TO 2014-05-21T10{noformat}
> Which parses as the year 2000 thru 2014 May 21st 10am (GMT). 
> I suggest this syntax because it is aligned with Lucene's range query syntax.
