Date histogram for Bucket Aggregation

Elastic Stack Elasticsearch
1

Hi,
I have a terms bucket aggregation on a field. is there a way to get the date histogram for each of the listed Bucket items received from terms aggregation.

Something like this. this isn't working but just to give the reference

{
    "query": {
        "bool": {
            "must": [ 
               SAMPLE_QUERY
            ]
        }
    },
    "aggs": {
        "category": {
            "terms": {
                "field": "category",
                "size": 200
            },
            "aggs": {
                "dates": {
                    "date_histogram":{
                        "field": "date",
                        "interval": "year",
                        "format": "yyyy"
                    }
                }
            }
        }
    }
}

from this, I'm expecting the Date histogram for each of the Bucket items that'll be returned.

Any suggestion will help greatly.

Thanks.
