Keyword Search in Databases: The Power of RDBMS
Summary: SQL-based keyword search over RDBMSs discovers interconnected tuple structures (connected trees, radius-bounded reachability, multi-center subgraphs) with size control. Tuple reduction prunes irrelevant tuples via SQL, then evaluates the reduced data with SQL; no new indexing, validated on two commercial RDBMSs and two real datasets.
