ldap_search by a numerical value

[Stephen Soltesz <soltesz@utk.edu>]

hello,

I've been looking around trying to figure out whether or not it is possible 
to search through an ldap database using a number's magnitude rather than as 
a string.

For instance is there a type for which a filter such as  
(&(volsize>=100)(volsize<=400)) would not return 40.


Is all processing in ldap string based?  Is there a nice way to search for 
ranges of numbers?

Thank you,
Stephen.
