Abstract
An extended search method and apparatus is provided. An interest term model of each user is established. An extended term model of each fourth search sequence is established. A corresponding extended search term is determined based on a current search sequence of a current user and based on an interest term model of the current user as well as an extended term model of the current search sequence; and a corresponding search result is provided for the current user based on the current search sequence and the extended search term. The present invention can implement simpler and more efficient personalized searches, and is advantageous in terms of meeting long-tail requirements of users (that is, adding personalized result recalling), reducing calculation and storage costs, universality, practicability, and the like.
