摘　　要：随着计算机技术和互联网技术的发展,人们也越来越多的使用电子文档记录数据,电子文档具有容量大,易存储和易转移等特点,但当数据量较大时查找电子文档的内容就需要借助索引技术加快搜索速度,索引技术的优劣直接影响用户的使用体验。主要探讨单机存储大规模文档时高效索引的建立问题,论文分析检索系统的组成和原理,最后使用Lucene工具包通过多线程建立多个索引目录的方式,加速索引的建立以及索引查询的速度。实验结果表明,该文的方法能有效提升索引的创建和搜索速度。With the development of computer technology and Internet technology,more and more people use electronic documents to record data.Electronic documents have the characteristics of large capacity,easy storage and easy transfer.However,when the amount of data is large,searching the content of electronic documents requires the help of index technology to speed up the search speed.The quality of index technology directly affects the user’s experience.This paper mainly discusses the establishment of efficient index when a single machine stores large-scale documents,analyzes the composition and principle of the retrieval system,and finally uses Lucene tool package to establish multiple index directories through too many threads to accelerate the establishment of index and the speed of index query.Experimental results show that the method of this paper can effectively improve the speed of index creation and search.
