A method and apparatus for rewriting of search engine queries is provided. Queries are rewritten by applying a set of rules. The rules represent domain knowledge and can be created by developers or users outside the search engine. There are two types of rules, production rules and definitions. Production rules specify how a query can be modified. Definition type rules specify a vocabulary for matching or modification of query terms. The modified query is issued to a search engine generating more focused and relevant results.
