Lucene一般使用StandardAnalyzer，对于中文采用单字分词方法，效果不是很好。
Lucene的contrib里有三个相关的中文分析器，CJKAnalyzer， ChineseAnalyzer和SmartChineseAnalyzer。其中CJKAnalyzer主要是双字分词，ChineseAnalyzer主要是单字分词，而SmartChineseAnalyzer使用语法分析和概率模型效果最好。
将学习1中StandardAnalyzer换成SmartChineseAnalyzer，添加lucene-smartcn-3.0.2.jar.
我从百度百科上copy一些编程语言的内容，用记事本保存。结果我的windows7 64enterprise（en）记事本没法保存中文，本来想转换成word文件，结果用wps打开也是乱码，只好重新copy。
运行参数：index/cntext data/cntext
运行结果：

执行搜索，运行参数：index/cntext 编程
结果eclipse好像不支持中文，出现错误：

哎，中文编程真是麻烦!
