Deprecated. Use `StandardTokenizer` instead, which has the same functionality. This filter will be removed in Lucene 5.0

    @Deprecated
    public final class ChineseTokenizer

extends org.apache.lucene.analysis.Tokenizer

Tokenize Chinese text as individual chinese characters.

The difference between ChineseTokenizer and CJKTokenizer is that they have different token parsing logic.

For example, if the Chinese text "C1C2C3C4" is to be indexed:

- The tokens returned from ChineseTokenizer are C1, C2, C3, C4.
- The tokens returned from the CJKTokenizer are C1C2, C2C3, C3C4.

Therefore the index created by CJKTokenizer is much larger.

The problem is that when searching for C1, C1C2, C1C3, C4C2, C1C2C3 ... the ChineseTokenizer works, but the CJKTokenizer will not work.
