David Smiley commented on SOLR-6103:
------------------------------------
It just occurred to me that {noformat}* TO 2014{noformat} ought to be supported
but it doesn't work -- I'll fix that in LUCENE-5648.
Perhaps the range syntax should include matching '[' and ']'? It's only
pertinent for indexing ranges; at query time you might as well use the normal
range query syntax. One aspect I haven't considered is exclusive boundaries,
but I think it's generally a non-issue because of the rounding this field
supports.
Note that LUCENE-5648 is still only v5/trunk for the moment.

> Project: Solr
> Issue Type: New Feature
> Components: spatial
> Reporter: 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.
