Title:
SYSTEM AND METHODOLOGY FOR A MULTI-SITE SEARCH ENGINE
Document Type and Number:
WIPO Patent Application WO/2010/045065
Kind Code:
A3
Abstract:
Techniques for query processing in a multi-site search engine. According to one embodiment, during an indexing phase, each site of a multi-site search engine indexes a set of assigned web resources and each site calculates, for each term in the set of assigned web resources, a site-specific upper bound ranking score on the contribution of the term to the search engine ranking function for a query containing the term. During a propagation phase, all sites exchange their site-specific upper bound ranking scores with each other. In response to a site receiving a query, the site first determines the set of locally matching resources and compares the ranking score of a locally matching resource with the site-specific upper bound ranking scores for the terms of the query that were received during the propagation phase and determines whether to communicate the query to the other sites.
