Abstract
One embodiment of the present invention provides a system that identifies a synonym for a query phrase in a manner that ensures that the synonym does not drop information from the query phrase. First, the system identifies a synonym for the query phrase and synonyms for sub-components of the query phrase. If the identified synonym for the query phrase is also a synonym for a subcomponent of the query phrase, the system does not use the identified synonym as a synonym for the query phrase.
