Example of getting a release(s) using the PropertyFilter in the query string

[JGCreator]

The API documentation doesn't list what the valid ids are for properties by which one can filter.

A comma-delimited list of extended properties to be retrieved. If set, the returned Release will contain values for the specified property Ids (if they exist). If not set, properties will not be included.

This seems like critical information if I need to know the id to filter by in order to get it populated.
