Aggregations 1.1.1 to 1.7.3 different results on Arrays

Elastic Stack Elasticsearch
1

Hi,

We have a problem with aggregations since we upgraded from 1.1.1 to 1.7.3 (yeah it's a bit of a huge jump)

what we want is to group by user and get the doc count

in 1.1.1 we filtered by

users.id = 1
aggregation term users.id

we got:
"key": 1
"doc_count:" 3

in 1.7.3
we get:
"key": DOC ID
"doc_count:" 1

"key": DOC ID
"doc_count:" 1

"key": DOC ID
"doc_count:" 1

this happens only to Arrays (not nested) and not inner objects.

{
"query": {
"filtered": {
"filter": {
"bool": {
"must": [
{
"terms": {
"users.id": [
"160"
]
}
}
]
}
}
}
},
"aggs": {
"users_group": {
"terms": {
"field":"users.id"
}
}
},
"size": 0
}

Can you provide us with an example that reproduces the issue?

Hello here you go

Query:

{
    "query": {
        "filtered": {
           "filter": {
               "bool": {
               "must": [
                 {
                     "terms": {
                         "users.id": [
                            "160"
                         ]
                      }
                  }
               ]
               }
           }
        }
    }, 
    "aggs": {
        "users_group": {
            "terms": {
                "field":"users.id"
                
            }
        }
    },
    "size": 0 
}

Mapping:
had to shorten the mapping a bit because 5000 max limit forum.
Hopefully nothing relating :slight_smile:
