Abstract
Presenting one or more suggested search-engine queries based on an initial search-engine query is described herein. Once the initial query is received, a search engine determines whether any web content is relevant thereto. If not, a query-suggestion service determines whether any suggested queries can be substituted for the initial query. If not, the query is spell-corrected, if necessary, and parsed into individual terms. Each parsed term is then checked to see whether it can be associated with alternative search terms. Terms than can are combined and their combination is also checked for alternative search terms. All of the alternative search terms are scored and then assembled into a list of suggested search terms that is presented to the user.
