Thanks David for clearing it out my doubts.
I added a patch which adds tests around 'dateRange' having multiple ranges.
For this I made 'dateRange' field multiValued in the solrconfig.

> 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.
