When you want to consider the values of the property as being a "set"
of values, then that is exactly the proper modeling construct to use.
This is particularly the case for the example you gave of wanting to
retrieve using any one of the values. So they really are independent
values

That is because you are probably trying to put the range on the
property itself. Properties have an independent existence, and any
range or domain information you attach to the property is global. It
affects all uses of that property.
If you want to restrict the values for a property just for a class
(and its subclasses), then you need to attach that restriction to the
class definition.
You can do this with an allValuesFrom or SomeValueFrom restriction
and use an enumerated set as the (anonymous) class definition that is
used in the restriction. For example:
P subclassOf ( key allValuesFrom {"A", "B", "C"} )
Q subclassOf ( key allValuesFrom {"D", "B", "E"} )

Yes. At least for names. It is used in the Protege interface to
search for values. It works like file name wildcards.
