Gus,
Perhaps you might try the technique described in the forwarded exchange
below. It has been working very nicely for me.

Hi,
You can do that via adding the following lines in managed-schema.
<dynamicField name="*_range" type="date_range" indexed="true"
stored="true"/>
<fieldType name="date_range" class="solr.DateRangeField"/>
<copyField source="*_date" dest="*_date_range"/>
After adding the above and re-indexing docs, you will get the result like
following.
{ "responseHeader":{ "status":0, "QTime":0, "params":{ "q":"*:*", "indent":
"on", "wt":"json", "_":"1528772599296"}}, "response":{"numFound":2,"start":0
,"docs":[ { "id":"test2", "meta_creation_date":["2018-04-30T00:00:00Z"], "
meta_creation_date_range":"2018-04-30T00:00:00Z", "_version_":
1603034044781559808}, { "id":"test", "meta_creation_date":[
"1944-04-02T00:00:00Z"], "meta_creation_date_range":"1944-04-02T00:00:00Z",
"_version_":1603034283921899520}] }}
thanks,
