The implications of Information Foraging Theory on designing user-centered websites have not gone unnoticed. Jakob Nielsen and Jared Spool, among others, have put forth considered recommendations on how to enhance information scent on the web. Most of their guidelines, however, tend to assume that the designer has direct control over the explicit words used in the interface. While this is certainly the case for browse-based websites dependent on site-wide navigation and hyperlinks, it breaks down for search interfaces where both content and navigation are completely dynamic.
While the principles for amplifying information scent in search-based interfaces are complimentary to those of browse-based models, they are yet distinct from them. Understanding how information scent applies to search first requires an understanding of human search behavior and the factors that affect it.
