Java Lucene NGramTokenizer

我不认为您会找到想要查找返回String的方法的内容。您需要处理Attribute。

应该像这样工作：

Reader reader = new StringReader("This is a test string");NGramTokenizer gramTokenizer = new NGramTokenizer(reader, 1, 3);CharTermAttribute charTermAttribute = gramTokenizer.addAttribute(CharTermAttribute.class);gramTokenizer.reset();while (gramTokenizer.incrementToken()) {    String token = charTermAttribute.toString();    //Do something}gramTokenizer.end();gramTokenizer.close();

不过，如果此后需要重用，请确保将Tokenizer重置（）。

每个注释的单词而不是字符的标记分组：

Reader reader = new StringReader("This is a test string");TokenStream tokenizer = new StandardTokenizer(Version.LUCENE_36, reader);tokenizer = new ShingleFilter(tokenizer, 1, 3);CharTermAttribute charTermAttribute = tokenizer.addAttribute(CharTermAttribute.class);while (tokenizer.incrementToken()) {    String token = charTermAttribute.toString();    //Do something}
