My problem:  
There are a lot of documents with the following structure (example):

{"someId" : 1, "someCounter": 2}  
{"someId" : 1, "someCounter": 1}  
{"someId" : 2, "someCounter": 3}  
{"someId" : 3, "someCounter": 5}  
{"someId" : 3, "someCounter": 1}  
{"someId" : 3, "someCounter": 3}

I want to calculate the percentile of the amount of the \*someCounter \*grouped  
by _someId_:

Request example

"aggs": {  
"someId": {  
"terms": {  
"field": "someId"  
},  
"aggs": {  
"someCounter\_sum": {  
"sum": {  
"field": "someCounter"  
},  
"aggs": {  
"percentile": {  
"percentiles": {  
// ?  
}  
}  
}  
}  
}  
}  
}

Response example

"aggregations": {  
"name": {  
"percentile": {  
"99.0": 0.001  
}  
}  
}

I’m trying to aggregate with _terms_, _sum_ and _percentiles_, but I’m not  
sure if it is possible. I also tried _script field_ with the same result.  
Is it possible to calculate percentile based on aggregated data on  
elasticsearch?
