For example, what people want (and are now getting) in product search is not a list of pages, but a set of products displayed in some meaningful fashion. They want a map of the product space, not a list.
举例来说，人们在搜索产品时想找的（现在找到的）并不是一系列网页，而是按一定顺序排列的产品组合。 他们想要的是产品领域的指示图，而不是简单的列表。 其中的难度当然在于每种产品都有自己特定的结构和特色。
