   Sounds good. However, I'm not entirely sure about the correctness of the 
weight calculation. Shouldn't the weight of the leading characters be higher 
(assuming the order of the strings is as in the dictionary)? Once the strings 
are accurately mapped to floats, I believe there wouldn't be any problem with 
calculating selectivity as you've proposed.
