Maybe. But in a both humorous and serious sense, this isn't a question of complexity being abstracted is it? It's simply transferring a solution to another medium. If not for software I'd solve the indexing issue the same way I would with paper. I'd have one paper that acts as an index across my books. Instead of using paper though I'm using a digital medium. So is that a case of abstraction?
