Beware of storing timestamps (DateFields, I guess) in Lucene, if you intend to use range queries (xxx TO yyy).
Why?
We have attributes that contain iso8601 date strings and when indexing:
Date date = isoConv.parse(value, new ParsePosition(0)); String dateString = DateField.dateToString(date); doc.add(Field.Keyword(name, dateString));
then when searching:
String from = DateField.timeToString(searchFromDate);
String to = DateField.timeToString(searchToDate);
RangeQuery rq = new RangeQuery(new Term(searchKey, from),
new Term(searchKey, to), true);Is this not correct?

my XML files contain something like
<date> <year>2004</year><month>04</month><day>27</day>... </date>
and I would like to sort by this date.
So I guess I need to modify the Documentparser and generate something like a millisecond field and then sort by this, correct?
Has anyone done something like this yet?
Thanks
