Abstract
An efficient information search mechanism provides control over the relaxation of a search query to users that are requesting searches. Through such a mechanism, a user can specify a sequence of sub-queries that is associated with variations of the main search criteria, and specify a progression in which to execute the sub-queries. Hence, users can impart their priorities with respect to search term variations used in relaxing the main search criteria, which further allows the users to impart their notion of the relevance of results that may be returned by particular sub-queries. A query that includes a sequence of sub-queries is received and the sub-queries are executed, if at all, by a database server in an order based on the progression specified by the user. Response time and network loading are improved through reduction of unnecessary work by the database server and through reduction of computationally costly communications between client and server and associated processing.
