This paper analyzes three kinds of multi-keywords weighted metasearching methods which are reported at home and abroad,points out the problem of neglecting the words order which exists in previous methods.This study puts forward multi-keywords synthesizing weighted method which combines the words order feature,and improves the current methods.The paper also studies the results fusion based on the D-S theory.The experiment indicates that the method proposed in this paper can improve retrieval performance obviously.
