It is also suitable for finding out how many resources match a given description; for this use, if all you want to know is if I<any> resources match the description, the bailout parameter will allow you to avoid potentially expensive enumeration of all matching resources.  Thus, this is suitable for cases where you don't want the structure, just a list of all resources.
