Get feedback on the keyword that was sent to the Twitter Stream API in creating Apache Storm topology

Question

I am developing a system that uses Apache Storm integrated with the Twitter4j library, to process tweets in real time. But I have a problem: Is there any way to know which keyword that originated that tweet returned?

Example:

//Palavras-chave para a criação da topologia do Storm
String keywords[] = {"Palavra 1", "Palavra 2"};

//Este método é chamado quando é retornado um tweet que contém aquela palavra-chave
  @Override
  public void execute(Tuple tuple, BasicOutputCollector collector) {
      Status status = (Status) tuple.getValueByField("tweet");
      System.out.println(status);
  }

//Resultado do Sysout
StatusJSONImpl{createdAt=Wed Sep 16 13:55:52 BRT 2015, id=645265788760587264, text='RT @user: Este é um tweet da Palavra 1' ... }

StatusJSONImpl{createdAt=Wed Sep 16 13:55:56 BRT 2015, id=645265788760587265, text='RT @user: Este é um tweet da Palavra 2' ... }

Is there any way to find the keyword that was used without making a string comparison loop (such as a foreach)?

I did not find any object attribute that has the keyword, only the data from tweet.
