The existing enterprise information search system has a lot of deficiencies. On the one hand,It can only provide a database search function,which can not search the information stored on the files of the server; On the other hand,in the case of massive information,the search speed of the database search function will be drastically reduced,and its performance often fail to meet requirements, even affect the normal use of the database.The enterprise information full text search system based on lucene has well met the data management and the search demand which proposed by the users of the enterprise.At the same time,it has satisfied the enterprise search system’s timeliness,the integrity and the secure request.The system has created full-text index for the database and the files stored in the server, provided users with a web search interface and provided a Web Service interface for other developers of the enterprise.The key problems in this system are as follows:build a suitable analyzer for the enterprise information full-text search system; create full-text index for the database and the files stored in the server;update the index timely; improve the user’s search experience based on DWR framework.This System is based on open source full-text search framework Lucene,which uses inverted index structure and full-text search strategy.As a result,the index structure and search efficiency has improved significantly.And the system has solved the defects of database search.The system also can search the information stored on the files of the server. In all,it’s a great convenience for users to manage and search the enterprise information.
