> As I was trying out dimensional fields for SOLR-8396, I realized that DimensionalRangeQuery
is not working with UninvertingReader. 
> In Solr, all directory readers are wrapped by an UninvertingReader and an ExitableDirectoryReader.

> Here's the error:
> {code}
> Exception in thread "main" java.lang.IllegalArgumentException: field="rating" was indexed
with numDims=0 but this query has numDims=1
