今天 用lucene完成了 一个简单的web应用，提取了早期编写的一个测试类， 首先简介下lucene几个常用包;
lucene 包的组成结构：对于外部应用来说索引模块(index)和检索模块(search)是主要的外部应用入口
org.apache.Lucene.search/ 搜索入口
org.apache.Lucene.index/ 索引入口
org.apache.Lucene.analysis/ 语言分析器
org.apache.Lucene.queryParser/ 查询分析器
org.apache.Lucene.document/ 存储结构
org.apache.Lucene.store/ 底层IO/存储结构
org.apache.Lucene.util/ 一些公用的数据结构
话不多说，直接上代码（这是早期封装的一个测试类，封装的还算比较完善，有兴趣的朋友可以在此基础上继续完善）：
