問題：
I couldn't think of any good examples other than the "how to count words in a long text with MapReduce" task. 除了“如何使用MapReduce計算長文本中的單詞”任務之外，我想不出任何好的例子。 I found this wasn't the best example to give others an impression of how powerful this tool can be. 我發現這不是給別人一個關於這個工具有多強大的印象的最好例子。
I'm not looking for code-snippets, really just "textual" examples. 我不是在尋找代碼片段，實際上只是“文本”示例。
