基于Lucene全文检索引擎的应用与改进

Application and Improvement of Lucene-based Search Engine

Lucene全文检索技术以其开放源代码的良好特性、优异的索引结构、有效的系统架构获得了广泛的应用。分析了Lucene的系统组织结构与核心类,同时指出其检索算法中的不足。给出了一个基于Lucence全文检索技术的信息导航系统中的设计。最后特别针对检索算法中的不足,设计和实现了利用PageRank算法的检索器。

Lucene was an excellent technology frame of full-text retrieval engine of open source code. It was widely used for outstanding characters of open source code, excellent indexed construction and ef（ective system construction. Initially, it analysed the architecture and the key classes of Lucene, and points out the disadvantage of search algorithm. Then, it gave the example in informative navigation system. Finally, search engine was designed and implemented using the pageRank algorithm, to overcome the shortage of searching algorithm in Lucene.
