I assume you meant to add ',d'in there. > then your index is as fat as your book, isn't it? Yes. And it still isn't as useful for any SELECT that doesn't use the fields in the right order. And it's more useful for a SELECT that does use those fields in the right order. And it's less useful if you ever want to read the text in an order that makes any sense: I cannot read the index to a text book and learn the information the textbook wants to teach me.
