基于Lucene的异构数据库全文检索技术

摘要

Recently the army has accumulated massive operational data,equipment performance,naval battlefield environment etc.These huge data is with various formats,and stored in different types of database.How to retrieve the target information from these data rapidly and exactly is a very important work.Lucene is a Java-based open source library of full text search,and can be easily used to customize a search engine which can meet the specific needs of users.In this paper,we develop a configurable full-text search engine which can support different types of database.%当前,我军积累了部队情况、装备性能、海战场环境等海量的作战数据.这些数据数量巨大、格式多样,且存储在不同类型的数据库中.如何快速准确地从这些数据中检索出目标信息,成为一项非常重要的工作.Lueene是一个基于Java的开源的全文检索库,利用它可以方便地定制出符合用户特定需求的搜索引擎.使用Lueene可研制出一种可配置的、支持不同类型数据库的全文搜索引擎.
