In recent years, with the development of Internet and its wide spread, more and more information resources and sites are available. And the information can be freely organized at the same time. On the Internet, the traditional ways of information finding is through the Internet explorer. Through the Internet explorer, a new page is available just by clicking the mouse and input the corresponding URLs. With more and more information, it is impossible to get the correct information quickly. The search engine is ranked as the second popular network tools. But compared with the fast development of the number of Internet information and the requirement of more precise information, the current search engine cannot catch up with them correspondingly. Thus, a more intelligent and personalized search engine is urgently needed. How to get exactly what the user need from the so many sources has become a hot topic in both scientific and practical areas.The following problems are rooted in most of the search engines available now.First, its high coverage and low full-query problems rank first. The dramatic increase on both the number and contents of the web pages make it impossible to setup a integrated index which may result in the false results.Second, the heterogeneity of the data types which are used to represent the Web information makes the interchange between different data formats impossible. Third, the user interfaces of the current search engine is not enough and deficient in interactive cooperation. Therefore, the user may have difficulties in defining some more precise query and subsequently they got the undesired result.Finally, the search results can not be ranked. And most often, the user have to search what they want again.All in all, intelligent searching technologies which can provide the user with the information the user want are urgently needed.In order to solve the above problems, based on the deepened research on the requirement of the education resources, with the comparison of different intelligent searching technologies, this paper proposed a new intelligent search method which can search multiple web pages that are similar in contents.This method first summarizes the web page information that is similar in order to have a initial understanding of the searching. The user can input the search key words and find the information they need. The system is personalized because it can provide the user with the information based on the dynamically changed pages and its contents.The method we proposed in this paper including the following five steps:(1) Accessing the web pages based on the IP address provided.(2) Make a deduction about the pages that will be needed next based on the current state of the searching activity and the pages that are currently opened.(3) Based on the result of the above steps to make a decision about whether the search is failed or not.(4) The searching is finished within the current pages, no matter it is failed or successful. And then give a full insight into the searching paths in order to supplement the knowledge base.(5) Repeat the above four steps until the predefined pages are all included. After a detailed research about the newly proposed method, this paper gives a full explanation about its practical performance in an education resource system. The education resource system is mainly used to provide the teaching materials. The teachers can login to the system pages to search the information they need. And more specifically, a professional teacher pays attention to the subject that he is majored. Thus, web pages that contain the information about this subject may frequently accessed by those teachers. The teachers pay close attention about the change of the contents, newly added information and so on. Besides, if the position where the target pages located changed or the organizational architecture changed, or even the hierarchical relationship changed, the teachers may have some problems when they access the page next time. And that is the place where the newly proposed search method can be used. Based on the customization of a specific user to the pages he needed, and with the help of constraint relations between different pages, the intelligent search system can provide the information that the users care about. And the intelligent search system can trace the changes happened on the pages that the users accessed before. Therefore, the intelligent search system can provide accurate and efficient information searching services. This is quite useful to some specific users.The intelligent system performs well now. It is highly appreciated in the education system, especially when it comes to the customization of the information services. With the great success of the development of the intelligent system, there are still some problems do existed. Thus, some functions should be taken into the future consideration.
