<GET index/_search

Current result:

"orders": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,
"buckets": [
{
"key": "301",
"doc_count": 4,
"sum_order_count": {
"value": 20
}
},
{
"key": "302",
"doc_count": 4,
"sum_order_count": {
"value": 20
}
},
{
"key": "303",
"doc_count": 5,
"sum_order_count": {
"value": 25
}
}
]
},
"total_sales": {
"value": 65
}
}
}
}
}
/>

Expected result:
<`"aggregations": {
"orders_over_time": {
"buckets": {
"2018-02-01T00:00:00.000Z": {
"key_as_string": "2018-02-01T00:00:00.000Z",
"key": 1517443200000,
"doc_count": 13,
"orders": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,
"buckets": [
{
"key": "301",
"doc_count": 4,
"rank":1,
"sum_order_count": {
"value": 20
}
},
{
"key": "302",
"doc_count": 4,
"rank":2,
"sum_order_count": {
"value": 20
}
},
{
"key": "303",
"doc_count": 5,
"rank":3,
"sum_order_count": {
"value": 25
}
}
]
},
"total_sales": {
"value": 65
}
}
}
}
}
/>

I want to get the position of only one key like 302 i.e. 2.

I don't think this is currently possible today, you'll just have to do the processing client side to find the position.
