Ok.. Thanks for your quick reply.
so as per document, i am following the steps. I tried to create new pipeline but i am getting an error, "parse_exception. No processor type exists with name [attachment]".
Could you please help me with this?

That's another question. Basically you did not install the plugin or you did not restart elasticsearch node.
