Lucene算法优化及其在P2P检索中的应用

Optimize Arithmetic Of Lucene And Apply In The P2P Search

随着P2P搜索引擎的地位日益重要,如何提高其分布式性能成为近年来的研究热点之一。同时,随着其广泛地应用,对于目前使用的P2P搜索引擎,还急需解决其检索结果中垃圾信息过多的问题。本文在详细分析相关工作原理的基础上,提出对Lucene算法中计算文档得分的评分公式进行优化,并将其应用于P2P检索,通过对查询所得的结果集进行二次排序,可以在查全率不变的情况下有效地提高检索效率。

In recent years, with the status of P2P has become more and more important, how to improve distributed performance of the P2P has become a research hotspot. At the same time, with its broad application, we are urgent to do resolve the problem that too much spam in the results searched by the P2P search engine at present. By optimizing the scoring formula of documents of Lucene ,and applying in the P2P programmer, this paper brings up a new design to effectively improve the search results through the second compositor for the results searched under the circumstances of the range of finding unchanged.
