Hi,

I wonder if there is any possibility to access upper level aggregation  
results in sub aggregation?

Example:

Run a terms aggregation and get "\_term" variable result in sub  
aggregations.

"aggs" : {  
"pairs" : {  
"terms" : { "script" : "\_source['pairs'].keySet()" }  
aggs: {  
"sum" : { "script" : "\_source['pairs'].get(_\_term_)" }  
}  
}  
}

\_term variable can be used for ordering of terms aggregation result but not  
available at sub-aggregation.  
It would be very nice if there is some way to provide it to sums  
aggregation. I found in documentation that \_value could be set outside  
script....

Best regards,  
Evgeny Ryabitskiy.
