If your attachments are in a location that's indexed by windows search, you can add them to universal search on the documents tab.
You will love this "free" program: "Everything" from www.voidtools.com Take the time to review the tutorial (I think there's a youtube video) to take advantage of it's ability to
search file content. If you have the CVs in nested directories this will work wonderfully for you. It indexes files so it's wicked fast. (Don't think it indexes content although it will read it).
If you take the time to add a line to the attachment (CV "shorthand") or better yet, save the file with a dominant skill keyword you WILL have your index!
