The predominant mechanisms for helping users find products in electronic catalogs are hierarchical navigation and text-based searches. Advanced electronic product catalogs also offer support for feature-based search or interactive product configuration. However, these search mechanisms are only appropriate if the space of products to be presented conforms to a number of simplifying restrictions. In this paper we describe an experiment in which we explored how the product space of Swiss health insurance offers, for which these simplifying assumptions do not hold, can be made accessible by combining mechanisms for feature-based search and interactive product configuration.
