Abstract
A search method is disclosed. In the method, a data rewriting system obtains, from a database, one or more search term candidates that are relevant to a present search term. The data rewriting system retrieves properties of the present search term and the one or more search term candidates, where the properties describe respective matching results of the present search term and the one or more search term candidates. Based on the matching results, the data rewriting system determines whether the present search term needs to be rewritten, and rewrites the present search term based on the matching results to provide a rewritten present search term in response to determining that the present search term needs to be rewritten. A search engine performs a search based on the rewritten present search term.
