Package org.apache.lucene.analysis.cn Description

Analyzer for Chinese, which indexes unigrams (individual chinese characters).

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 the analyzers/smartcn package): Index words (attempt to segment Chinese text into words) as tokens.

Example phrase： "我是中国人"

1. StandardAnalyzer: 我－是－中－国－人
2. CJKAnalyzer: 我是－是中－中国－国人
3. SmartChineseAnalyzer: 我－是－中国－人
