"exists" queries ([* TO *]) on DateRange fields return 0 results regardless of docs in the index with values in that field.
The issue appears to be that the query is converted into a NormsFieldExistsQuery, even though DateRangeField uses omitNorms=true by default. Probably introduced by
SOLR-11746's changes to these optimizable range queries.
I've attached a script to reproduce the issue (tested on Solr 8.6.2) and screenshots showing showing schema and query-parsing info for the reproduction.
