Sorry, my mistake. I glanced at your message and leapt to
the wrong conclusion. Don't know what is wrong in your code
but since I had been meaning to get to grips with Date
searching in Lucene but had never made time to do so, have
knocked up a test program, attached to this message, which
creates a small index and searches on a few ranges, including
0 to 2008269714990, and it seems to work fine. Perhaps it
may help you track down your problem.
If not, and you still want help, I suggest you post the
simplest possible program that demonstrates the problem.
