CoreData - how to retrieve a particular value (not object)

Subject: CoreData - how to retrieve a particular value (not object)

If I have object Foo with a variable bar (a string) as an NSManagedObject, is it possible to run a fetch request /query (something) to return a set of all values of bar? Why I want to do this is I want to execute a fetch request to retrieve all instance of Foo where bar == someValue.
