How to improve the accuracy of the search algorithm is important for its search algorithm improvement. This paper researches an algorithm based on the user’s model. First, it defines a group of Search-Models.Each Search-Model contains a User-Model and an information resequence tactic. When the user does a searching, Vector Space Model will be used to choose an optimal Search-Model, and then uses the information resequence tactic defined in the Search-Model to resequence the information found by user’s input. Finall, it sends the information to the user making user attribute as the premise to filter and re-sequence the information. It provides accurate search service according to the user’s specific conditions. Results show that the algorithm can improve the accuracy with an acceptable time consumption.
