/**
 * Analyzer for Simplified Chinese, which indexes words.
 *
 * @lucene.experimental  Three analyzers are provided for Chinese, each of which treats Chinese
 *     text in a different way.
 *     
 *       StandardAnalyzer: Index unigrams (individual Chinese characters) as a token.
 *       
CJKAnalyzer (in the analyzers/cjk package): Index bigrams (overlapping groups of two
 *           adjacent Chinese characters) as tokens.
 *       
SmartChineseAnalyzer (in this package): Index words (attempt to segment Chinese text
 *           into words) as tokens.
 *     
 *     Example phrase： "我是中国人"
 *     
 *       StandardAnalyzer: 我－是－中－国－人
 *       
CJKAnalyzer: 我是－是中－中国－国人
 *       
SmartChineseAnalyzer: 我－是－中国－人
 *     
 *
