Distributed Query Processing on the Web [PDF]
Proceedings of 16th International Conference on Data Engineering (Cat. No.00CB37073), 2005 CurrentWeb querying systems are based on a "data shipping" mode wherein data is downloaded from remote sites to the user-site, queries are processed locally against these documents, and then further data is downloaded from the network based on these results.
