基于Lucene对文件全文检索的研究与应用

Research and Application of Full-text Retrieval Technology for Document Based on Lucene

分析了Lucene的原理,针对Lucene的IndexReader、IndexSearcher、IndexWriter、Directory的各种不足,研究了不同优化方案,并通过重写源码中的QueryParser限制效率低下的通配符查询及模糊查询,提高了搜索响应速度,最后,文章研究了Lucene的多个应用领域。

This paper analyses the principles and application of Lucene,according to the shortage of IndexSearcher,IndexWriter,Directory,it puts forward some methods to optimize them.and forbids WildcardQuery and FuzzyQuery which is inefficient by override the source code of QueryParser to raise the response speed,at last many applications about Lucene are researched in the paper.
