Design And Implementation Of A Enterprise Search Platform

At present, the enterprise the age of information explosion, the size of the enterprise, the bigger the accumulation of the more information, information retrieval and inquires the work also more difficult. Now many of the enterprise has been set up their own internal network (Intranet), and such network scale is more and more big, the data is the more and more, the data type is also more and more rich, resulting in the user to find out in the data that you are interested in information more and more difficult, without the help of search engines do this seems to be getting more impossible.The enterprise search is refers to search the enterprise internal resources and related enterprise external resources, it different from general Internet search, Has the following features:various data sources, data structure complex, search results accurate, strict information security, retrieval service intelligence, search information real-time etc.Based on the J2EE architecture, the full-text search engine Lucene and Tika middleware used to build enterprise search platform, the construction of enterprise success the search platform. This system is internal and external corporate diversification of information collected based on the unity of the custom task, and collected massive information of intelligent analysis and effective integration, using a secure role-based and unified access interface, providing enterprise information retrieval service. This system focused on improving enterprise information use efficiency, promoting the enterprise productivity and efficiency, achieve enterprise maximizing the value.First, the background information, the main problems of this thesis are introduced. Next, related technologies used in the system are generally introduced. Then, the system is analyzed with the help of data flow diagram. In system design, the overall design of the system is given, then according to the division of functions of this system, the detail of each function module is introduced using module diagram, and some E-R diagrams and database tables are provided in the end. In implementation, flow chart is used to describe the implementation detail of each main module. Description of the system unit testing, integration testing, and system test, and demonstrate the operating results. At last the conclusion to this thesis and the outlook of it are given for further study.
