i'm trying to create new index with data from the existing index , could you suggest me the best approach to do that.

EXISTING SAMPLE INDEX STRUCTURE (INDEX-1):  
{  
"name": "arun",  
"my\_list: ["john", "peter", "julie"]  
}

RESULT NEW INDEX STRUCTURE (INDEX-2):  
{  
"name": "john",  
"my\_list: ["john", "peter", "julie"]  
}  
{  
"name": "peter",  
"my\_list: ["john", "peter", "julie"]  
}  
{  
"name": "julie",  
"my\_list: ["john", "peter", "julie"]  
}

basically i want all of the my\_list in INDEX1 needs to be individual document in INDEX2.
