Hi friends,
I am an admin making the transition to developer so forgive me if this is/should be considered common knowledge but...
I was wondering if someone would be able to help me write a test class for this Dynamic Search Page controller.  I understand in theory how to write a test class but I'm not sure i would be able to successfully pull it off on my own.  

Any help would be MUCH appreciated!
