【摘要】：Lucene是一個(gè)優(yōu)秀的開源的全文搜索技術(shù)框架,按照框架規(guī)范,擴(kuò)展它的功能,可以將它很好地嵌入到搜索引擎中。研究了Lucene的索引結(jié)構(gòu)和原理,通過改進(jìn)增量索引、增大索引緩沖區(qū)的大小和減少往磁盤上寫索引文件的頻率,達(dá)到提高創(chuàng)建索引效率的目的。設(shè)計(jì)了全文檢索實(shí)驗(yàn),實(shí)驗(yàn)結(jié)果表明,該方法使10 000篇文檔創(chuàng)建索引的平均效率比前人方法提高了19.5%,具有良好的應(yīng)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.
