Dear Erick,
Thanks for the idea, it doesn't work. It raises an exception that the
value is missing the double() method.
Best,
George

You _might_ (and I haven't tried this) be able to use sorting by
funtion with min/max for a date range field, see: "Sort by Function"

Solr understand that I have used single timestamps?
No. It could theoretically, but sorting just isn't implemented in
DateRangeField.
I have even stored the dates.
My problem is that I need to use the query formating stated in the
documentation:
https://lucene.apache.org/solr/guide/7_1/working-with-dates.html#date-range-formatting
For example, if "financialYear" is a date range, I can do
q=financialYear:2014 and it will return everything that has a date
within 2014. If the field is date point, will it work?
Yes, just query with the plain old range syntax:
q=financialYear:[2014-01-01T00:00:00.000Z TO 2015-01-01T00:00:00.000Z}
DateRangeField might be slightly faster for such queries, but that
doesn't really matter much. I only used normal date fields yet, usually
they're fast enough.
As a rule of thunb, only use DateRangeField if you really need to index
date ranges.
