"Today, I'd like to share with you a hidden gem inside of Windows Vista's search capabilities. It's a neat little feature that lets you build one saved search on top of another, and we call it Query Composition. Think composition in the mathematical sense, not in the context of writing an English paper. To explain this feature, I'd like to start by talking a bit about Libraries."
