With the development of the Internet and information technology, it also expands constantly in the field of education at present. As for the teachers, students, parents and other education workers in the higher education, accurate extraction of network resources not only helps the users to obtain rapidly the information they need, but also makes the teachers improve their working efficiency, enables the students enrich their knowledge and makes the parents master the latest education information. The paper combines service mode of acquiring Web resources of the higher education based on analyzing the characteristics of the users demanding higher education resources, constructs flexible and high-efficiency distributed and parallel retrieval system to solve the problem of low accuracy for the users to acquire higher education resources with convenient retrieval mode and high-efficiency query process. And the paper starts from search behaviors of the users to study individualized service mode with the basis of user interest and service mode of active push, which can improve time-validity for the users to acquire information. Introduction Searching engine, special website of subjects and integrated website of higher education is the mode which is often used by the users to acquire higher education resources. And searching engine is the most commonly used. Comprehensive application of searching engine is convenient for the users to search online information to some extent, but because it is for the public, emphasizes commonality and search results have a lot of clutter information which has low accuracy, it can't satisfy the needs of higher education users. Most users input one or more keywords for search query, but there are usually two kinds of information after the inquiry by searching multiple keywords, resource category information and subject description information. And search engine can't understand accurately the meaning in certain education field, which result in clutter and excessive information in retrieved results. Therefore, we should dig deep into the resources in this area, filter irrelevant information and make strict and careful classification based on professional needs of higher education users and advantages of topic-specific search engine, which can provide professional information service for higher education users, reduce the time of the users filtering information and make the users invest time and energy into reading and using the information. Introduction of system development platform JAVA technology. The most important reason why JAVA technology is selected to develop languages and implement system is that the nature of JAVA is more applicable to the development of application technology for all kinds of enterprises. And JAVA is the preferred technology platform to development languages, especially the server side of JAVA has evident characteristics of developing applications which are embodied in the following aspects. (1) Independence. It can be applied conveniently in all kinds of enterprises, and there is no need to rewrite the code and recompile for different platforms. International Conference on Education Technology, Management and Humanities Science (ETMHS 2015) © 2015. The authors Published by Atlantis Press 355 (2) Reusability of the code. Java is a language which could be reused and provides a reusable mechanism within the system. JAVA system provides special enterprise-version software which has more evident and better reusable structures for JAVA language. (3) Modularity. The means of applying modularity in JAVA includes JAVA Servlet, Java Server Pages(JSP)and Enterprise JavaBeans(EJB). And applications are divided into layers with clear functions by applying 3 layers or multilayer structure. J2EE system platform. The reason for choosing J2EE platform is that the platform has some advantages which are embodied in the following aspects. The above-mentioned JAVA language can obtain backwards support from J2EE system computing platform, which can make some standard development and application in J2EE system platform skip their own platform and transplant into other platforms for application. At the same time, the written code are safer and more reliable. It is convenient for the enterprises to use the platform, and the platform provides most services which are needed in calculation for enterprise and it is easy to use. Most ports such as JDBC,JNDI,and JAVA MAIL are made standard definition. SQL Server Database. SQL Server 2000 has introduced some new servers and database, which not only makes the function improve, but also makes it have more practical and convenient features, that is, XML supporting and new data types including BIGINT SQL_VARIANT and TABLE. It is convenient for user-defined functions, indexing function improves greatly, which is embodied in creating index in calculating the list. And the function of full-text retrieval improves a lot, indexed views becomes more concise and beautiful. Distributed query function and the type of trigger improved greatly. Cascading referential integrity constraints. At last, Collation function improves, that is, Collation substitutes for Sort Orders and Code pages. Network Structure Design of System The system uses B/S framework, so the corresponding web server is needed. The connection diagram of hardwares for the whole system is shown in Fig. 1. Fig. 1 Connection diagram of hardwares As indicated above, the relative and the needed web pages are grasped from external internet and are transferred to database and web server. The related operations are carried out in the way of accessing the Web server and are imported into content delivery system. If the server system has better performance, it can combine data acquisition server and database server, and only one computer can be for all operations when te related operations are carried out. Establishment of Indexes Realization of resources searching technique. The process of establishing indexes is to extract relevant data from database. And the record of each line automatically generates Document, then the document is written in index file, and the corresponding document is joined with the corresponding method of Lucene.
