The future is in the past: Designing for exploratory search


Exploratory search activities tend to span multiple sessions and involve finding, analyzing and evaluating information and collab-orating with others. Typical search systems, on the other hand, are designed to support a single searcher, precision-oriented search tasks. We describe a search interface and system design of a multi-session exploratory search system, discuss design challenges en-countered, and chronicle the evolution of our design. Our design describes novel displays for visualizing retrieval history infor-mation, and introduces ambient displays and persuasive elements to interactive information retrieval.
