lucene的中文分词器

lucene的中文分词器到现在还没有好的解决办法。下边介绍了两个lucene自己提供的分词器和一个javaeye上的网友实现的分词器。关于各个分词器的不同见代码中的print信息。直接运行得到console的输出结果更容易对比不同。

// 中文分词使用了Paoding的分词技术，特表示感谢
public class TestCJKAnalyzer {
  private static String testString1 = "中华人民共和国在1949年建立，从此开始了新中国的伟大篇章";

  private static String testString2 = "比尔盖茨从事餐饮业和服务业方面的工作";

    Token t;
    while ((t = ts.next()) != null) {

    }

    }
  }

  public static void main(String[] args) throws Exception {

    String testString = testString1;
    System.out.println(testString);
    testStandard(testString);
    testCJK(testString);
    testPaoding(testString);

老大，你的中文分词到哪下载的。我的lucene 包里怎么没有CJKAnalyzer 和chineseAnalyzer啊
