Bertino E., Gibbs S., Rabitti F. Document Query Processing Strategies : cost evaluation and heuristics. In: Conference on Office Information Systems (Palo Alto, California (USA), 23 - 25 March 1988). Proceedings, pp. 169 - 181. Robert B. Allen (ed.). ACM, 1988.
This paper describes query processing strategies used in a system where queries are specified on formatted data and text components of documents. The system provides different access methods: indexes for formatted data and signature files far the text. Four basic document queries, representative of a wide range of queries, are examined in detail. Strategies for query processing are presented together with an evaluation of the costs of the various strategies. Finally, general heuristics are derived.
