Class ChineseTokenizer


public final class ChineseTokenizer
extends Tokenizer

Title: ChineseTokenizer Description: Extract tokens from the Stream using Character.getType() Rule: A Chinese character as a single token Copyright: Copyright (c) 2001 Company: The difference between thr ChineseTokenizer and the CJKTokenizer (id=23545) is that they have different token parsing logic. Let me use an example. If having a Chinese text "C1C2C3C4" to be indexed, the tokens returned from the ChineseTokenizer are C1, C2, C3, C4. And the tokens returned from the CJKTokenizer are C1C2, C2C3, C3C4. Therefore the index the CJKTokenizer created is much larger. The problem is that when searching for C1, C1C2, C1C3, C4C2, C1C2C3 ... the ChineseTokenizer works, but the CJKTokenizer will not work.
