EConsultancy has a great post on why retailers need effective feature filtering.

I know a lot of people are unfamiliar with this concept, and it goes by other names as well (most notably: “guided navigation.”) The non-obvious benefit of this type of technology (supplied by industry leaders as Endeca In-Front, Right Now Technologies, and IBM Omnifind) is that it can effectively turn a search utility on your site into a strategic selling platform. Search becomes more than something users expect and can instead provide them with an unexpected and delightful brand experience.
