Unfortunately I need a date range field, e.g [2000-05-01 TO 2019-06-02].
DatePointFields can't represent that as far as I know.

There is a field type in the schema called pdate:
<fieldType name="pdate" class="solr.DatePointField" docValues="true"/>
This should work for you.
The timeseries Streaming Expression uses the JSON facet API for range
faceting and works really well.

Hi,
I'm trying to have a range facet on a field of type solr.DateRangeField.
As far as I can tell, this isn't possible with JSONFacet, only with the
old facet system - a quick google turns up several other people with the
same problem. When using JSONFacet I get problems with this line of
code:
https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/search/facet/FacetRange.java#L255
It looks like during the change to JSONFacet the range facets have been
restricted to only allow Trie or PointField fields. Is this likely to be
fixed in future updates, or were there problems with using
DateRangeFields? I could use the old parameter facet system, but there
are features in JSONFacet I need.
For completeness, the error I get:
