Fagni T., Orlando S., Palmerini P., Perego R., Silvestri F. A Hybrid Strategy for Caching Web Search Engine Results. In: Twelfth International World Wide Web Conference (www2003) (Budapest, Hungary, 20-24 May 2003). Proceedings, p. 156. Irwin King and Tamas Maray (eds.). 2003.
This work discusses the design and implementation of an efficient caching system aimed to exploit the locality present in the queries submitted to a Web Search Engine (WSE). We enhance previous proposals in several directions. First we propose the adoption of a hybrid strategy for caching, and then we experimentally demonstrate the superiority of our hybrid strategy. Further we show how to take advantage of the spatial locality present in WSE query logs by exploiting a sort of adaptive prefetching strategy.
