Elasticsearch term aggregation with range doc count

Question

I want to aggregate a field and return only those buckets in which doc count is within 10 to 20 for eg

So far from documentation it says that we can provide min_doc_count parameter.

Is there any way we can provide max_doc_count also so i only get required buckets ?

Thanks

you can use the following query to filter the buckets using bucket_selector aggregation. You can take a deep look at pipeline aggregations and buckets paths here .

In the following example i am aggregating the document on product.name field where product is of type object for me.

{
    "size": 0,
    "aggs": {
        "values": {
            "terms": {
                "field": "product.name.raw",
                "size": 10
            },
            "aggs": {
                "final_filter": {
                    "bucket_selector": {
                        "buckets_path": {
                            "values": "_count"
                        },
                        "script": "params.values > 10 && params.values < 20"
                    }
                }
            }
        }
    }
}

Hope this helps Thanks
