Analyzer for Simplified Chinese, which indexes words.
WARNING: This API is experimental and might change in incompatible ways in the next release.
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"
  1. StandardAnalyzer: 我-是-中-国-人
  2. CJKAnalyzer: 我是-是中-中国-国人
  3. SmartChineseAnalyzer: 我-是-中国-人
