如何将Rapidminer的输出写入txt文件？

我正在使用Rapidminer 5.3。我取了一个包含约三个英语句子的小文档，将其标记化并根据单词的长度对其进行过滤。我想将输出写入另一个单词文档中。文档实用程序，但是它不起作用，它只是将相同的原始文档写入新文档。但是，当我将输出写入控制台时，它给了我预期的答案。写文档实用程序出了点问题。
这是我的过程

i am using rapidminer 5.3.I took a small document which contains around three english sentences , tokenized it and filtered it with respect to the length of words.i want to write the output into a different word document.i tried using Write document utility but it is not working,it is simply writing the same original document into the new one.However when i write the output to the console,it gives me the expected answer.Something wrong with the write document utility. Here is my process

阅读文档->令牌->过滤令牌- >写文档

READ DOCUMENT --> TOKENIZE --> FILTER TOKENS --> WRITE DOCUMENT
