I would like to get result only 3 documents from 5 documents. And the 3 document is not duplicate categoryName. Please share me the solution for this case.  
My document sample here:  
{  
"took": 1,  
"timed\_out": false,  
"\_shards": {  
"total": 5,  
"successful": 5,  
"failed": 0  
},  
"hits": {  
"total": 5,  
"max\_score": 1,  
"hits": [  
{  
"\_index": "store",  
"\_type": "product",  
"\_id": "hello3",  
"\_score": 1,  
"\_source": {  
"name": "One touch",  
"image": "dd",  
"price": 2.5,  
"status": 1,  
"categoryName": "Health",  
"popular": 2  
}  
},  
{  
"\_index": "store",  
"\_type": "product",  
"\_id": "hello4",  
"\_score": 1,  
"\_source": {  
"name": "Touch Top",  
"image": "dd",  
"price": 2.5,  
"status": 1,  
"categoryName": "Health",  
"popular": 2  
}  
},  
{  
"\_index": "store",  
"\_type": "product",  
"\_id": "hello2",  
"\_score": 1,  
"\_source": {  
"name": "Apple touch",  
"image": "dd",  
"price": 12.5,  
"status": 1,  
"categoryName": "Mobiles & Tables Edit",  
"popular": 2  
}  
},  
{  
"\_index": "store",  
"\_type": "product",  
"\_id": "hello1",  
"\_score": 1,  
"\_source": {  
"name": "Touch today",  
"image": "dd",  
"price": 2.5,  
"status": 1,  
"categoryName": "Mobiles & Tables Edit",  
"popular": 2  
}  
},  
{  
"\_index": "store",  
"\_type": "product",  
"\_id": "hello5",  
"\_score": 1,  
"\_source": {  
"name": "Touch Tola",

}
