Description

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 org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:462)
	at DimensionalRangeQueryExample.query(DimensionalRangeQueryExample.java:66)

Here's an example program to trigger this failure:

		uninvertingMap.put("rating", UninvertingReader.Type.INTEGER);
		reader = UninvertingReader.wrap(reader, uninvertingMap);

		IndexSearcher searcher = new IndexSearcher(reader);

		Query legacyQuery = LegacyNumericRangeQuery.newIntRange("rating_legacy", 1, 4, true, true);
		Query dimensionalQuery = DimensionalRangeQuery.new1DIntRange("rating", 1, true, 4, true);

		System.out.println("Legacy query: ");

		reader.close();
	}

	private static void query(Query q, IndexSearcher searcher) throws IOException {
		int hitsPerPage = 10;
		TopDocs docs = searcher.search(q, hitsPerPage);
		ScoreDoc[] hits = docs.scoreDocs;

		System.out.println("Found " + hits.length + " hits.");
		for(int i=0;i<hits.length;++i) {
			int docId = hits[i].doc;
			StoredDocument d = searcher.doc(docId);
			System.out.println((i + 1) + ". " + d);
		}
	}
	private static void addDoc(IndexWriter w, String title, int rating) throws IOException {
		Document doc = new Document();
		String id = ""+new Random().nextInt(1000);
		byte idBytes[] = id.getBytes();
		doc.add(new StringField("id", new BytesRef(idBytes), Store.YES));
		doc.add(new TextField("title", title, Field.Store.YES));
		doc.add(new DimensionalIntField("rating", rating));
		LegacyIntField legacy = new LegacyIntField("rating_legacy", rating, Store.YES);
		legacy.setIntValue(rating);
		doc.add(legacy);
		w.addDocument(doc);
	}
}

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