Lucene全文索引效率的改进
发布时间：2019-05-18 09:03
【摘要】：Lucene是一个优秀的开源的全文搜索技术框架,按照框架规范,扩展它的功能,可以将它很好地嵌入到搜索引擎中。研究了Lucene的索引结构和原理,通过改进增量索引、增大索引缓冲区的大小和减少往磁盘上写索引文件的频率,达到提高创建索引效率的目的。设计了全文检索实验,实验结果表明,该方法使10 000篇文档创建索引的平均效率比前人方法提高了19.5%,具有良好的应用前景。
[Abstract]:Lucene is an excellent open source full-text search technology framework, according to the framework specification, expand its functions, can be well embedded in the search engine. The index structure and principle of Lucene are studied. by improving the incremental index, increasing the size of index buffer and reducing the frequency of writing index files to disk, the efficiency of index creation can be improved. The full-text retrieval experiment is designed. The experimental results show that the average efficiency of 10,000 documents index creation is 19.5% higher than that of the previous methods, and has a good application prospect.
