        "value" : "5942178562002.65",   
        "dataset" : "GDP (current US$)",
        "data" : [
                { 
                        "data_name" : "country",
                        "value" : "india"
                },
                {
                        "data_name" : "date",
                        "value" : "2011"
                }
        ]
},  
{
        "_id" : "23423q53qdsfsd5",       
        "value" : "1234238562002.65",   
        "dataset" : "GDP (current US$)",
        "data" : [
                {
                        "data_name" : "country",
                        "value" : "india"
                },
                {
                        "data_name" : "date",
                        "value" : "2012"
                }
        ]
}

it suppose to be one result

{
        "_id" : "23423q53q45345",       
        "value" : "5942178562002.65",   
        "dataset" : "GDP (current US$)",
        "data" : [
                { 
                        "data_name" : "country",
                        "value" : "india"
                },
                {
                        "data_name" : "date",
                        "value" : "2011"
                }
        ]
}
