```
search_month = model.search().query(q_objects)
search_month.aggs.bucket(
        source_month, 'date_histogram', field='date',
        interval=date_ranges[source_month].interval,
    )
response_month = search_month.execute()

```

Unfortunately, it gives me all data from the model - **but how to show only results of aggregations - count of documents ?**

Set `size` parameter to `0`.

Unfortunately looks like cannot use size=0 on **aggregations** with **date\_histogram**. Perhaps its just **elasticsearch\_dsl** python library problem ?

```
TransportError(400, 'illegal_argument_exception', '[date_histogram] unknown field [size], parser not found')
```

I don't know this client but my guess is that it should be something like:

```auto
.search().query(q_objects).size(0)

```
