Subject Re: JSON Facet doesn't allow date range facets
Date Thu, 12 Dec 2019 11:40:55 GMT
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.
