             Summary: Add DateRangeField
                 Key: SOLR-6103
                 URL: https://issues.apache.org/jira/browse/SOLR-6103
             Project: Solr
          Issue Type: New Feature
          Components: spatial
            Reporter: David Smiley
            Assignee: David Smiley


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.
