The invention discloses an information search method, an information search system and an information search device. According to the method, when the second level cache search is carried out in a search cluster system, aiming at each subset of a search server set and according to the corresponding relation between the calculation result and each search server in each subset, the search server corresponding to a calculation result which is obtained by carrying out calculating on a keyword on the basis of the setting algorithm can be respectively selected, and the search request can be responded by using the selected search server; apart from the first response including the search request of a keyword, the selected search server caches a document list corresponding to the keyword, therefore, the selected search server can directly read the cached document list, the duration of the search can be shortened, the search cluster system resource occupied in the information search process can be reduced and the performance of the search cluster system can be improved. |
