I tried your suggestion and was able to get the indexing to work (I assume it's
correct), but now the search is throwing an error...
unexpected docvalues type SORTED_NUMERIC for field 'Planned Completion
Date' (expected=NUMERIC). Use UninvertingReader or index with docvalues.
My search code:
topDocs = FacetsCollector.search(searcher, q, null, MAX_HITS, new
Sort(new SortField("plannedCompletionDate", SortField.Type.LONG,
!sc.isAscending())), false, false, fc);
My index code:
//copied from
http://stackoverflow.com/questions/31451111/lucene-5-sort-problems-uninvertedreader-and-docvalues
public static final FieldType LONG_FIELD_TYPE_STORED_SORTED = new
FieldType(LongField.TYPE_STORED);
static {
LONG_FIELD_TYPE_STORED_SORTED.setDocValuesType(DocValuesType.SORTED_NUMERIC);
LONG_FIELD_TYPE_STORED_SORTED.freeze();
}
doc.add(new LongField(field.toString(),
time,LONG_FIELD_TYPE_STORED_SORTED));
doc.add(new SortedNumericDocValuesField(field.toString(), time));
Any ideas?
Thanks in advance

Subject: [EXTERNAL] Re: Multivalued DocValuesField
You need to use a SortedNumericDocValuesField, which allows for multiple
numeric values to be stored per-document. I’m not sure if that’s in Lucene
5.0, though, you may need to upgrade to something more recent.
