甲骨文信息检索系统的设计与实现

Design and Realization of Oracle Information Retrieval System

甲骨文研究中的信息资源非常丰富,但是从这浩瀚的资源中如何快速、全面并且精确地查找到用户所要查找的信息,这是一个令所有研究者头疼的一个问题,快速、精确的搜索引擎就是解决这个难题的最佳方法,但在实践中发现单个搜索引擎很难达到既精确又查全率高的目的。文章提出了一个全文搜索引擎与元搜索引擎相结合的基于Java混合型搜索引擎,它利用了Java的跨平台性和多线程性来设计这个混合型搜索引擎,使它既有全文搜索引擎的精确性又有元搜索引擎的查全性的,从而可以快速地为用户查找到更准确、全面的信息。

The information resources in oracle study are very abundant,but from this vast resources how fast and comprehensively and accurately find the information used for the user,which is a annoying problem to researcher.The best way to solve the problem is a fast and accurate search engine.But in practice,designing a single search engine is difficult to achieve the purpose of accurate.So,this thesis proposes a hybrid search engine based on Java with a combination of meta-search engine and full text search engine,it used the Java cross-platformability and multi-thread attribute to realize this hybrid search engine,which not only realize full-text search engines＇ accuracy,but also realize the meta-search engine＇s advantages of comprehensive searching,the search engine helps the users to find more accurate,comprehensive information.
