摘要：
With computer and network technology developing, the educational resources on the Internet are also growing exponentially. To locate useful resources from the mass and diverse information is crucial. When using general search engine to search information in a specific field, the results usually cover all fields which can't provide accurate retrieval service for users. However, powerful vertical search engine can meet users' information needs more precisely. This paper describes a vertical search engine on the resources in educational field based on Lucene. Three parts of the system are detailed in this paper, identification of search results metadata, analysis and indexing of all formats of resources and improvement of Lucene ranking algorithm.
