Hi Everyone,

I like to use elasticsearch aggregations to achive my task but problem is that my document contains nested object and i want to apply aggregations on nested object. so please help me in it. please find the below sample data and my requirement

I have documents like below:  
[  
{  
"name": "Item 1",  
"resellers": [  
{  
"reseller": "companyA",  
"price": 450  
},  
{  
"reseller": "companyB",  
"price": 400  
}  
]  
},  
{  
"name": "Item 2",  
"resellers": [  
{  
"reseller": "companyA",  
"price": 350  
},  
{  
"reseller": "companyB",

},  
{  
"name": "Item 3",  
"resellers": [
