Hi,

I have several aggregations each of which have their own inner  
aggregations. It seems that the 'min\_document\_doc' does not apply when  
their containing aggregation is itself empty. I presumed that because both  
level of aggregations use 'min\_document\_doc' there would be buckets for the  
inner agg as well.

Can somebody enlighten me on why ES cannot do this, sort of a technical  
insight would be appreciated.

Thanks.

Here is a snippet of my query:  
...  
"aggregations": {  
"totalCount": {  
"global": {}  
},  
"categories-missing": {  
"terms": {  
"field": "categories.missing",  
"size": 0,  
"min\_doc\_count": 0,  
"order": {  
"\_term": "asc"  
}  
}  
},  
"datasetId": {  
"terms": {  
"field": "datasetId",  
"size": 0,  
"min\_doc\_count": 0,  
"order": {  
"\_term": "asc"  
}  
},  
"aggregations": {  
"attributes-Default": {  
"terms": {  
"field": "attributes.Default",  
"size": 0,  
"min\_doc\_count": 0,  
"order": {  
"\_term": "asc"  
}  
}  
},  
"attributes-Administrative\_information": {  
"terms": {  
"field": "attributes.Administrative\_information",  
"size": 0,  
"min\_doc\_count": 0,  
"order": {  
"\_term": "asc"  
}  
}  
},  
...
