Q: Calendar - search with period?

This knowledge base article (http://support.apple.com/kb/TS4337#Remove_Unusable_and_Duplicate_Events) instructs one to list all events from a selected calendar by entering a period in the search field.  I wish that worked.  However, for me it only finds events that contain a period somewhere in them.  I think this article is dealing with old versions or something.  Is there any way that currently works to show all events in the list?
