      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:

      Exception in thread "main" java.lang.IllegalArgumentException: field="rating" was indexed with numDims=0 but this query has numDims=1
      	at org.apache.lucene.search.DimensionalRangeQuery$1.scorer(DimensionalRangeQuery.java:186)
      	at org.apache.lucene.search.Weight.bulkScorer(Weight.java:135)

      	at DimensionalRangeQueryExample.query(DimensionalRangeQueryExample.java:66)

      Here's an example program to trigger this failure:

      		doc.add(new DimensionalIntField("rating", rating));
      		LegacyIntField legacy = new LegacyIntField("rating_legacy", rating, Store.YES);

      I don't yet know more as to why this could be. Michael McCandless Any ideas, please?
      Apologies if I should've brought this up in the mailing lists, or as a comment in LUCENE-6917 itself.
