Exception thrown when using a terms aggragation as nested under a composite aggregation.  
The query is ok on small indices but the problem starts after about 2m+ documents.  
Any ideas?

My query:  
POST my\_index/\_search  
{  
"query": {  
"match\_all": {}  
},  
"size": 1,  
"aggs": {  
"comp": {  
"terms": {  
"field": "yrow.5"  
},  
"aggs": {  
"nested": {  
"terms": {  
"field": "field2",  
"order": {  
"\_key": "desc"  
}  
}  
}  
}  
}  
}  
}
