Question

长时间的用户，但新的海报，我有一个非常令人沮丧的问题，我似乎无法调试。我有一个程序在进行理论练习的语音搜索。输入通过标准输入接收。所以，

Java MyAppication Jones Smith Andrews < NAMES.TXT

从那里，搜索项被推入Hashmap，NAMES.TXT也被推入HashMap。对剥离某些字符（如元音）的值执行操作。

例如：Jones作为目录[“Jones”] = Jns存储在Directory Hashmap中搜索词哈希映射也是如此。

这是搜索方法，

  private static String search(){
  Iterator<String> searchKeyIterator = search.keySet().iterator(); 
  Iterator<String> directoryKeyIterator = directory.keySet().iterator(); 
  String output = new String();

  //Loop through the search terms
  while(searchKeyIterator.hasNext()){
      String searchkey = searchKeyIterator.next(); 
      Pattern searchRegex = Pattern.compile(regexBuild(search.get(searchkey))); 

      output += "\n" + searchkey + ": ";

      while(directoryKeyIterator.hasNext()){
          String directorykey = directoryKeyIterator.next();

          Matcher m  = searchRegex.matcher(directory.get(directorykey));
          boolean b = m.matches();

          if(b == true){
              output += directorykey + ", ";

          }
      }

      output = output.substring(0, output.length() - 2);
  }
    return output;}

它通过遍历搜索目录并为每个术语形成正则表达式模式（这是因为对等效字符的约束）。然后将此正则表达式与目录进行匹配。

例如，琼斯的输入变为Jns，这个的正则表达式变为[CGJKQSXYZcgjkqsxyz] [MNmn] [CGJKQSXYZcgjkqsxyz]，这意味着任何匹配JNS，SNS，Cng的东西都会匹配。

然而，它似乎不匹配。这是存储的数据集

key: Smith value: Smt
key: Johnson  value: Jnsn
key: Ericsson  value: Ercssn
key: Smyth value: Smt
key: Macdonald  value: Mcdnld
key: Smid  value: Smd
key: Schmidt  value: Scmdt
key: Smithers  value: Smtrs
key: Jonas  value: Jns
key: Nest O'Malett  value: Nst Mltt
key: Smythe  value: Smt
key: Van Damme value: Vn Dmm
key: Erikson  value: Erksn
key: Saunas  value: Sns
key: Johns  value: Jns

但结果似乎表明尽管看到列表中有一个，但没有匹配。

非常感谢任何帮助。

尽管输入正确，但Java似乎与正则表达式不匹配
