Migration Lucene 4 -> Lucene 6

Hi,

When I'm trying to launch search with ordering, but it fails with exception : unexpected docvalues type NONE for field 'LOCAL_TIME' (expected=NUMERIC). Re-index with correct docvalues type.

For indexing:


doc.add(new LongPoint("longValue", (Long) value));
doc.add(new StoredField("longValue", (Long) value));


For searching:

Sort sort = new Sort(new SortField("longValue", SortField.Type.LONG, false)

searcher.search(query, max, sort);


ð  unexpected docvalues type NONE for field 'LOCAL_TIME' (expected=NUMERIC). Re-index with correct docvalues type.

Do I have to reindex all my data, or can I change the way to do the search ?
If I have to reindex, what is the correct way to index with sort capabilities ?

Thanks

Ludovic BERTIN

Hi,

You need to add a NumericDocValuesField here as well - Point is for searching, Stored is for display.
