public final class HMMChineseTokenizerFactory
extends org.apache.lucene.analysis.TokenizerFactory

Factory for HMMChineseTokenizer

Note: this class will currently emit tokens for punctuation. So you should either add a WordDelimiterFilter after to remove these (with concatenate off), or use the SmartChinese stoplist with a StopFilterFactory via: words="org/apache/lucene/analysis/cn/smart/stopwords.txt"

Since:

4.10.0

WARNING: This API is experimental and might change in incompatible ways in the next release.
