Is Blackboard content searchable?

From BbWiki

Yes, you can search for items by file name, or perform a full text search for keywords within course content and uploaded files such as Word, text or pdf documents. To search across all Blackboard sites you have access to, enter the search term in the 'Search Blackboard' box on the upper right corner of the screen. To search within a particular course, navigate to the Search box in the course's Tools area.
