1. An information search method, comprising:
determining feature information of a target user;
acquiring at least one candidate search path to determine candidate search results in a database;
determining a matching degree between the feature information of the target user and the at least one candidate search path using a matching model, and determining a target search path from the at least one candidate search path according to the matching degree; and
determining a target search result matched with the target user using the target search path;
wherein a construction way of the at least one candidate search path comprises:
determining initial feature information of all data in the database, the data serving as search results obtained through the at least one candidate search path;
updating the initial feature information, using the matching model according to the feature information of the target user, to obtain updated feature information;
clustering the updated feature information to obtain search results with different levels of abstraction; and
constructing the at least one candidate search path using the search results with different levels of abstraction.
