Subject Re: Order by date

Thank you, Terry. But I need to do it without additional classes or smth.
I just can not understand the problem... I've tried to reindex the stuff
with

doc.add(Field.Keyword("_published", DateField.dateToString(date)));

and to search with

      Query query = new RangeQuery(null, new Term("_published",
DateField.dateToString(new java.util.Date())), true);
      DateFilter filter = DateFilter.Before("_published", new
java.util.Date());
      Hits hits = searcher.search(query, filter);

maybe, I misunderstand how to use this filter? Does RangeQuery automatically
order results by field? Looks like it should... people in the mailinglist
says, that my first approach works well (when encoding date to string with
pattern(yyyyMMdd), but iam still lobotomized;(
Phil.
