DISCOVER: Keyword Search in Relational Databases

Summary: keyword-only search over relational DBs; returns qualifying joining networks of tuples containing all query keywords. two-stage: Candidate Network Generator enumerates join networks; Plan Generator builds reusable plans; optimal plan NP-hard; greedy yields near-optimal costs; experiments show tuning.
