Elasticsearch - Count duplicated and unique values for a nested field - elasticsearch

Question

Elasticsearch - Count duplicated and unique values
I need also same kind of count but that field is in nested properties as
[{
"firstname": "john",
"lastname": "doe",
"addressList": [{
"addressId": 39640,
"txt": "sdf",
}, {
"addressId": 39641,
"txt": "NEW",
}, {
"addressId": 39640,
"txt": "sdf",
}, {
"addressId": 39641,
"txt": "NEW"
}
]
}, {
"firstname": "jane",
"lastname": "smith",
"addressList": [{
"addressId": 39644,
"txt": "sdf",
}, {
"addressId": 39642,
"txt": "NEW",
}, {
"addressId": 39644,
"txt": "sdf",
}, {
"addressId": 39642,
"txt": "NEW"
}
]
}
]
what would be the query for addressId duplicate counts ? Need you help on this user:3838328

I got the answer for nested field duplicate counts as
POST <your_index_name>/_search
{
"size": 0,
"aggs": {
"prop_counts": {
"nested": {
"path": "addressList"
},
"aggs": {
"duplicate_aggs": {
"terms": {
"field": "addressList.addressId",
"min_doc_count": 2,
"size": 100 <----- Note this
}
},
"duplicate_bucketcount": {
"stats_bucket": {
"buckets_path": "duplicate_aggs._count"
}
},
"nonduplicate_aggs": {
"terms": {
"field": "addressList.addressId",
"size": 100 <---- Note this
},
"aggs": {
"equal_one": {
"bucket_selector": {
"buckets_path": {
"count": "_count"
},
"script": "params.count == 1"
}
}
}
},
"nonduplicate_bucketcount": {
"sum_bucket": {
"buckets_path": "nonduplicate_aggs._count"
}
}
}
}
}
