   if opr=="range":
       if 'min' in opr_args: lo = min(keys)
       else: lo = None
       if 'max' in opr_args: hi = max(keys)
       else: hi = None

So, when min is specified, it takes the lowest values from the keys list, 
and when max is given, it takes the highest value from the list. No order 
is imposed, and you can specify any nuber of values.

{'level': (1, 4), 'level_usage': 'range:min:max'} is all that is needed, in 
fact, you can get away with {'level': 4, 'level_usage': 'range:min:max'}, 
but that wouldn't be much use =).

My mistake for not making it clear that the last example would work even 
tough it had four items in the search values list.
