摘　　要：针对有色冶金信息化服务平台文献资源检索功能的开发,综合运用Lucene.net、盘古分词等系列开源工具包,并结合中文分析器,对存储于数据库中的文档信息建立索引;根据用户提交的关键字信息,实现文献资源高效检索的功能.文章针对普通串行方式对大数据创建索引的低下效率,提出了一种能够适应现代多核计算机架构来提升建立索引性能的算法.通过该算法在获得性能提升的同时,也提高了程序的可扩展性.Based on the development of literature resources retrieval function of Information Service Platform for Nonferrous Metallurgy, this paper synthetically takes advantage of open-source toolkit such as Lucene.net, Pangu segmentation etc., and resorts to Chinese analyzer to index the document information storing in the database. In accordance with the keywords information submitted by the users, the system can achieve the efficient retrieval of literature resources. Considering the low efficiency of the index of large data in a common general serial way, a kind of algorithm which can adapt to modern multi-core computer architectures to improve indexing performance is put forward. The algorithm not only promotes performance, but also improves the expansibility of application.
