A search feature, if done well, is a good way to get to exactly what you want, quickly and easily. But the whole of human experience is not built on getting only what you're looking for. Lots of what we come to love gets accidentally discovered while browsing at random. It's a more time-intensive activity where things are not necessarily handed to you on a silver platter, but it can lead to some very rewarding experiences. This is why so many web catalogues need categories, featured products and suggestions. Search is only half the picture.
