I use a query to find the duplicates in an index based on a field. Some documents have the same value in this field and they are duplicates.

```auto
{
    "size": 0,
    "aggs": {
        "duplicate_terms": {
            "terms": {
                "field": "id.keyword",
                "min_doc_count": 2,
                "size": 50
            },
            "aggs": {
                "duplicate_documents": {
                    "top_hits": {
                        "size": 100
                    }
                }
            }
        }
    }
}

```

The ids can have different numbers of duplicates, for example, one can have 48, and another 7. Now it returns all the documents for a specific id, up to 100. Is there a way to set the size dynamically based on doc\_count for every bucket, so that it returns 47 documents for one id, and 6 for another?  
If it could return the duplicates except one

`doc_count - 1`
