BTW, one way to accomplish that is to transform your data into geometric shapes and then index them accordingly. Prior to the work Jeff Davis has done on time intervals it was common to treat time as points and ranges as lines or boxes. While we no longer need to play those games for time, I don't think there's an equivalent for non-time datatypes. -- Jim C.
