Viewing corel clipart with scrapbook X4

I am having a problem with the scrapbook feature and I apologize if this question has already been answered.  When I use scrapbook "search" to view the corel clipart that I downloaded to my hard drive, it won't look for it.  It only wants to look at my X4 disk.  I can view the files through scrapbook but I can't search the files (example, I can't type in "owl" and have it come up with all of the owl files from the corel clipart on hy hard drive).  Is there a way to fix this issue?  Thanks!
