在这里给大家来一些关于lucene in action的一些东东
你可以到:了解更新，更全的关于lucene的信息。
下面我做的demo，分享给大家：
项目结构：
运行Index时，美国空间，Run Configurations：
[两个参数之间有空格]
args[0] = “C:\Users\hongjie\Desktop\hongten_temp\hongten_index”;
args[1] = “C:\Users\hongjie\Desktop\hongten_temp\lucene-3.5.0”;
运行效果：
运行Searcher时，Run Configurations：
[两个参数之间有空格]
args[0] = “C:\Users\hongjie\Desktop\hongten_temp\hongten_index”;
args[1] = “cnhances”;
运行效果：
