基于Lucene的企业级搜索引擎的设计与实现

The enterprise-level search engine is proposed to solve the problem that enterprise have abundant document information resources but lack of effective search tools.The function and the overall framework of the enterprise-level search engine are analyzed firstly.Lucene indexer is studied in depth during implementation secondly.Then the plug-in unit is used to carry out the analysis and extraction of different types of documentsi in design.A set of parallel multi-task scheduling mechanism is established in the task scheduling.When the user interface is designed,Yui-ext components and DWR remote object invocation framework is applied to implement asynchronous communication by the Web,which can promote the users' experience.
