java+lucene中文分词，来看看百度究竟是怎么找到你想要的（十分重要，楼主幸苦之作）

我想只要是学过数据库的孩纸，不管是mysql，还是sqlsever，一提到查找，本能的想到的便是like关键字，其实去转盘网（分类模式）之前也是采用这种算法，但我可以告诉大家一个很不幸的事情，like匹配其实会浪费大量的有用资源，原因这里不说了请自己想一想，我们还是直接摆事实验证。

现在用去转盘网搜：hello 找个单词，如下：

http://www.quzhuanpan.com/source/search.action?q=hello&currentPage=1

翻页你会发现只要是包含hello的单词都找到了，但是如果你用like的话是不会有这个效果的，不信让我们再看一下，还好他来说电影网的分词算法我还没来得及修改，还可以看到现象：

http://www.talaishuo.com/searchResult.do?searchFileName=hello

你会发现只有开始包含hello这个字段的搜索串才能得到匹配，这就问题来了，数据库中大量的资源岂不是白白浪费了，不过没事，伟大的人类还是很聪明的，发明了分词，分词的原理我就不讲了，请自己百度吧，还是直接上代码，提示，这里需要四个jar包作为工具，我先上传的去转盘，想要做分词的请先下载：

注意由于去转盘网（http://www.quzhuanpan.com)是部署到linux上的，所以DISC_URL可以更具系统变换，我是通过url来判定索引文件是否唯一的，你可以更具id来判断，具体情况具体对待吧。

数据库之类的请不要关心，看思路即可，你如果需要换成你的即可，这里就不多说了。

看最后的部分：

pack

age com.tray.indexData;

import java.sql.SQLException;

public class Application {

    public static void main(String[] args){
        /*IndexFile indexFile=new IndexFile();
        indexFile.indexInit();
        try {
            indexFile.Index6Data();
        } catch (SQLException e1) {
            e1.printStackTrace();
        }
        indexFile.indexEnd();*/

        IndexFile indexFile1=new IndexFile();
        indexFile1.indexInit();
        try {
            indexFile1.Index3Data();
        } catch (SQLException e1) {
            e1.printStackTrace();
        }
        indexFile1.indexEnd();

            System.out.println("[高级检索花费时间：" + c + "毫秒]");

你可以在一个applicationic程序中开始索引，也可以写个定时器来定时索引，看需求。以上代码是楼主幸苦的作品，转载请不要改动，本人确保代码完全可用。
