Faceted search techniques integrate navigational (e.g., Yahoo!) and direct search (e.g., Google) to help users determine which portions of a classification contain the information desired. In other words, they combine browsing and search, leading to a mixed-initiative mode of interaction (Perugini & Ramakrishnan, 2003). While faceted classifications enumerate all possible path permutations to each terminal object in the presentation of hyperlinks, faceted search does not enumerate any, but rather uses search to achieve multiple access paths to the same item. While complementary in this respect, both approaches can be used in concert (leading to what is called faceted browsing and search) and, if implemented properly, the two integrate seamlessly.
