absolutely... gotta pad with zeros for place... even better maybe add a
alpha as the first character so leading zeros don't get dropped by

Something like :
(&(00067>minRangeBoundary)(00067<=maxRangeBoundary))
would work, I think (assuming that you store IDs between 0 and 999 999)

What if you set a minRangeBoundary and maxRangeBoundary attribute for
all of the objects you were searching?
then you could do something like this...
(&(67>minRangeBoundary)(67<=maxRangeBoundary))
