Methods, systems, and apparatus, including computer program products, to perform operations relating to processing query terms in a search query presented to a search engine. In one aspect, a method includes determining a query language from the query terms and the language of a user interface. In another aspect, a method includes using the interface language to select one or more mappings and using the mappings to simplify each query term; and applying each simplified query term to a synonyms map to identify possible synonyms with which to augment the search query. In another aspect, a synonyms map is generated from a corpus of documents. In another aspect, a method includes identifying one or more potential synonyms for a query term by looking up simplified query term in a synonyms map, the synonyms map mapping each of a plurality of keys to one or more variants, each variant being a word associated with one or more document languages. |
