Re: Simple date/range question
MMDD is the format You Timestamp contains HH mm, and ss, that's likely why your second query doesn't match anything. Drop everything other than MMDD from the index, and things should work.

Re: Simple date/range question
Let me clarify what Otis meant as well as shed some light on the other
questions in this thread.
On Apr 2, 2004, at 10:03 AM, [EMAIL PROTECTED] wrote:
if (time != null) doc.add(Field.Keyword(date, new
Date(time.getTime(;
query:
date:[20030101 TO 20030202]
date:20030101
The first query does throw a ParserException, the second doesn't
return any
hits.
QueryParser uses DateFormat.SHORT to parse dates using the default
locale. 20030101 does not parse using that format string.
If you are truly only representing dates (not times) then use, what
Otis meant, MMDD *Strings* to represent the date. If you need
times as well, first be aware of what RangeQuery does (expand all terms
in that range!) so that you aren't shocked with performance or a too
many clauses exception.
When you use Field.Keyword(String, Date), the date is converted into a
lexicographically ordered value (the ugly thing you saw in Luke). This
is why, if you only care about dates, MMDD is recommended (it must
sort properly).
Hmm...there must be something simple I misunderstood :) BTW what about
custom
date format in QueryParser (...and are the last two digits actually
the day
or month)?
Custom date format in QueryParser is quite do-able. Subclass
QueryParser and override getRangeQuery and do what you like there.
I do something similar in Lucene in Action. I'd like users to search
on ranges like lastmodified:[1/1/04 TO 12/31/04], but internally I
represent dates as MMDD. To make the conversion, I had to have a
custom QueryParser
/**
* From Lucene in Action (Manning Publications)
*/
public class SmartDayQueryParser extends QueryParser {
public static final DateFormat formatter =
new SimpleDateFormat(MMdd);
public SmartDayQueryParser(String field, Analyzer analyzer) {
super(field, analyzer);
}
protected Query getRangeQuery(String field, Analyzer analyzer,
String part1, String part2,
boolean inclusive)
throws ParseException {
try {
DateFormat df =
DateFormat.getDateInstance(DateFormat.SHORT,
getLocale());
df.setLenient(true);
Date d1 = df.parse(part1);
Date d2 = df.parse(part2);
part1 = formatter.format(d1);
part2 = formatter.format(d2);
} catch (Exception ignored) {
}
return new RangeQuery(new Term(field, part1),
new Term(field, part2),
inclusive);
}
}
