Abstract
A system determines whether a received search query includes an entity name, determines whether to rewrite the received search query based on information relating to prior searches involving the entity name, and rewrites the received search query when it is determined that the received search query should be rewritten. The system further determines whether to provide a suggestion of rewriting the received search query, as a rewriting suggestion, based on information relating to prior searches involving the entity name when it is determined that the received search query should not be rewritten. The system also generates the rewriting suggestion when it is determined that the rewriting suggestion should be provided. The system performs a search based on one of the received search query and the rewritten search query to obtain search results, presents the search results, and presents the rewriting suggestion when it is determined that the rewriting suggestion should be provided.
