Hi, I have documents in the index with the field sentimental\_keywords:

```auto
sentimental_keywords: [
{
    rate: 0.2857143,
    keyword: "manager"
},
...
{
    rate: -0.333333343,
    keyword: "project"
},
]

```

When I do terms aggregations :

```auto
"aggs": {
     sentimental_keywords": {
            "terms": {
                "field" : "sentimental_keywords.keyword.keyword",
                "size": 100
            }
}

```

I get the result:

```auto
'buckets': [
    {'key': 'manager', 'doc_count': 444},
    {'key': 'project', 'doc_count': 373}
]

```

I also want to add each term (key), the value of the rate, for example, get next result:

```auto
'buckets': [
    {'key': 'manager', 'doc_count': 444, 'rate': { 'value': 0.2857143}},
    {'key': 'project', 'doc_count': 373, 'rate': { 'value': -0.333333343}}
]

```

Do you have any suggestions?

I'm not sure if that would fit with what you're looking for as aggregations are meant to aggregate documents and not providing individual values.

So what about a `avg` or a `max` agg as a sub aggregation of your `terms` agg?

I've tried to use sub aggregation for a rate like `max` or `avg` , it returns the average or max rate for a document where term from top-level `aggs` meets.

I solved it by using sub aggregate terms for rate value

```auto
"aggs": {
    "sentimental_keywords": {
            "terms": {
                "field" : "sentimental_keywords.keyword.keyword",
                "size": 10
            },
            "aggs": {
                "rate": {
                    "terms": {
                        "field": "calculation.sentimental_keywords.rate",
                        "size": 1
                    }
                }
            }
            
        }
    }

```

In the result I get what I wanted:

```auto
{
     'key': 'project',
     'doc_count': 371,
     'rate': {
           'doc_count_error_upper_bound': 66,
           'sum_other_doc_count': 1789,
           'buckets': [{'key': -0.333333343, 'doc_count': 371}]
     }
}

```

I'm surprised that this will work with more data.
