Parent-child supports a
children aggregation as
a direct analog to the nested aggregation discussed in
Nested Aggregations. A parent aggregation (the equivalent of
reverse_nested) is not supported.
This example demonstrates how we could determine the favorite hobbies of our employees by country:
GET /company/branch/_search
{
"size" : 0,
"aggs": {
"country": {
"terms": { 
"field": "country"
},
"aggs": {
"employees": {
"children": { 
"type": "employee"
},
"aggs": {
"hobby": {
"terms": { 
"field": "employee.hobby"
}
}
}
}
}
}
}
}
