AB> What would be the best way to store this in lucene so I can do a range query?

AB> Also for all you smart people out there do you know the

AB> What I mean is if the long is constant what is the distance

AB> 32.74213 - 32.74212   = .00001 = ?distance?
AB> 32.74222 - 32.74212   = .00010 = ?distance?

AB> Thanks,
