+Analyzer for Chinese, Japanese, and Korean, which indexes bigrams (overlapping groups of two adjacent Han characters).
+<p>
+Three analyzers are provided for Chinese, each of which treats Chinese text in a different way.
+<ul>
+ <li>ChineseAnalyzer (in the analyzers/cn package): Index unigrams (individual Chinese characters) as a token.
+ <li>CJKAnalyzer (in this package): Index bigrams (overlapping groups of two adjacent Chinese characters) as tokens.
+ <li>SmartChineseAnalyzer (in the analyzers/smartcn package): Index words (attempt to segment Chinese text into words) as tokens.
+</ul>
+
+Example phrase: "我是中国人"
+<ol>
+ <li>ChineseAnalyzer: 我-是-中-国-人</li>
+ <li>CJKAnalyzer: 我是-是中-中国-国人</li>
+ <li>SmartChineseAnalyzer: 我-是-中国-人</li>
+</ol>
