Lucene拼写检查器3.6字符集

Question

我需要帮助设置lucene拼写检查器的字符集（3.6版的核心lucene和拼写检查器）。我的字典（“D:\dictionary.txt”）既有英语单词，也有俄语单词。我的代码与英文文本配合得很好。例如，它返回单词“hello”的正确拼写。但它不适用于俄语。例如，当我拼错一些俄语单词时，编译器引发异常（线程“main”java.lang.ArrayIndexOutOfBoundsException中的异常：0），它找不到任何关于俄语单词的建议。

这是我的密码：

        RAMDirectory spellCheckerDir = new RAMDirectory();
        SpellChecker spellChecker = new SpellChecker(spellCheckerDir);
        StandardAnalyzer analyzer = new StandardAnalyzer(Version.LUCENE_36);
        IndexWriterConfig config = new IndexWriterConfig(Version.LUCENE_36, analyzer);
        InputStreamReader isr = new InputStreamReader(new FileInputStream(new File("D:\\dictionary.txt")), "UTF-8");
        PlainTextDictionary dictionary = new PlainTextDictionary(isr);
        spellChecker.indexDictionary(dictionary, config, true);
        suggestions = spellChecker.suggestSimilar("hwllo", 1); // word 'hello' is misspeled like 'hwllo'

基于您的代码，我可以提供的最佳选择（非常有用，10倍）。我刚刚分别加载了两个词典，它们也可以在组合文件中使用。

    RAMDirectory spellCheckerDir = new RAMDirectory();
    SpellChecker spellChecker = new SpellChecker(spellCheckerDir);
    StandardAnalyzer analyzer = new StandardAnalyzer(Version.LUCENE_44);
    IndexWriterConfig config = new IndexWriterConfig(Version.LUCENE_44, analyzer);
    InputStreamReader isr = new InputStreamReader(new FileInputStream(new File("d:/dictionaries/English/words.english")), "UTF-8");
    PlainTextDictionary dictionary = new PlainTextDictionary(isr);
    spellChecker.indexDictionary(dictionary, config, true);
    isr = new InputStreamReader(new FileInputStream(new File("d:/dictionaries/Swedish/words.swedish")), "UTF-8");
    PlainTextDictionary swdictionary = new PlainTextDictionary(isr);
    spellChecker.indexDictionary(swdictionary, config, true);
    String wordForSuggestions = "hwllo";
    int suggestionsNumber = 5;

    String[] suggestions = spellChecker.suggestSimilar("hwllo", suggestionsNumber); // word 'hello' is misspeled like 'hwllo'
