With the development of Web technologies and the improvement of information technology standards, Internet has entered an age of information explosion. However, extraneous information is displayed on the top of the search results and the user interest in the search results in a text match without or seldom taking into account the search intents of the users. For most of the search engines, they either cannot become aware of the user interest properly or cannot find the information which users need efficiently. In our study, we solve these problems. We store users' search history in the user profile, and relocate the results of search history by the particular subject. The proposed method can provide a personalized search service that imparts higher priority to the user documentation saw, which is positioned at the top of the search results. On the basis of the proposed method, we developed a system with which the corresponding experiment has been performed to verify our proposed method. The experiment result shows the validity of our proposed method and the importance of personalized search.
