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?

I’m not sure if that’s in Lucene 5.0, though, you may need to upgrade to something more recent.
