Extended fact finding (vague query) What cities did John McCain live in since he became a Senator?
Exploration of availability (vague result request) What genealogical information on Barack Obama is at the National Archives?

Open-ended browsing and problem analysis (hidden assumptions) How has John McCain’s position on the environment changed since 2001?
Mismatch with metadata (requires exhaustive search) How has Barack Obama’s choice of clothing changed during his campaign?

Discovery Process: Design Challenges
Enrich query formulation
Expand result management
Enable long-term effort
Enhance collaboration
Deal with special cases: - Legal, patent & medical searches require thoroughness - Proving non-existence is difficult - Outlier items can be critical - Bridging items can be critical
