There is another way of looking at the statement -
 all customers in Indiana and Ohio
which seems simpler to me than producing the new phrase -
 all customers in Indiana  AND all customers in Ohio
instead of doing this why not treat Indiana and Ohio as a new single
conceptual entity giving -
 all customers in (Indiana and Ohio).

This seems simpler to me. It would mean the database would have to
allow aggregations of this type, but I don't see that as being
particularly problematic.

Have I missed some subtle point here?
