java - Nutch Crawling Result as JSON -

I'm using apache-nutch-2.1 to crawl. Is crawled results possible in Jason's form? I wrote a Java program to crawl using apache-nutch-2.1. How do I change crawled results as JSON? It may be a silly question, but when I google it There is no relation to this.

How will I find the crawled results Jason?
