说我有一个父文件
curl -XPUT es-host:9200/index/parent_type/1 -d '{
"foo": "bar"
}'
我有一个 child 证件
curl -XPUT es-host:9200/index/child_type/?parent=1 -d '{
"child-foo-1": "child-bar-1",
"child-foo-2": "child-bar-2"
}'
有什么办法可以在父文档聚合下获取我的子文档数据的子聚合，例如，
{
"aggregations": {
"foo-aggregations": {
"buckets": [
{
"key": "bar",
"doc_count": 1,
"child-foo-1-aggregations": {
"key": "child-bar-1",
"doc_count": 1
},
"child-foo-2-aggregations": {
"key": "child-bar-2",
"doc_count": 1
}
}
]
}
}
}
最佳答案
curl -XPOST 'localhost:9200/index/parent/_search?pretty' -d '
{
"size": "0",
"aggs" : {
"name" : {
"terms" : {
"field": "name.keyword"
},
"aggs" : {
"child_category": {
"children" : {
"type": "child_type_name"
},
"aggs" : {
"data" : {
"terms" : {
"field": "child_field_text.keyword"
}
}
}
}
}
}
}
}'
