Listen to Uwe.

Keeping your date/time in milliseconds is the best solution.

You don't care about how the user likes his data DD.MM.YYYY (Europe)
of MM.DD.YYYY(US), about timezones, daylight saving changes, leap
seconds, or any other complications.

Your dates are simple long numbers, you can easy sort them, do ranges
and whatever you like.

RE: about some date store

Hi,

Use NumericField and NumericRangeQuery to query. For sorting use the
corresponding datatype. In the numeric field you would parse the date to a
number (e.g. milliseconds since epoch) and index it using NumericField. To
print them, use SimpleDateFormat or whatever to convert the numeric value
back to a date after you got the results.

So "content" is a String variable in your program holding a multi-line
value, is it?  I'd double check exactly what that is holding before
you store it in the index.

I had done that,I used the docment.add(new
field("content",content,field.store.yes,filed.analyzer.yes));i have used
while loop to set the content like while((str=reader.readline)!=null) ,But
when i used document.get("content"),i can only get the first LIne.

You can only show that is stored (Field.Store.YES). Only then can
you use document.get(...) and get something to display
