To export indexed data from elastic search to otherwhere

Hi,
I have indexed data on elastic search node. The structure of document is it has two fields namely , name and message. In message it contains text. Now I want to export the indexed data into any other place.
The structure of document is
{
"name":"xyz",
"message":"i like to eat king's burger. I go there quite often"
}

I am not able to export these data because it do not store in text file, I am quite new in elastic search. Your help is highly appreciated.
