I managed to do an update\_by\_query script with elasticsearch\_dsl.

```auto
response = ubq.script(source="pm_data_source.hw_alias' = params.new_ap_name",lang="painless",params={"new_ap_name": new_ap})\
        .query("match", pm_data_source.hw_alias = old_ap ).execute()

```

Current problem is: in the `query()` I am unable to match fields inside an object. Do you happen to know how to do this?

Solved with the following:

```auto
update = ubq.script(source="ctx._source.object_name.field_name = params.new_ap_name; ctx._source.radio.Accesspoint_name = params.new_ap_name; ",
         lang="painless",
         params={ "new_ap_name": "new_field_value" }).update_from_dict({
                    "query": {
                           "bool": {
                                  "must": [
                                         { "match": { "object_name.field_name": "new_field_value" } },
                                         { "match": { "account_name": "Filters documents of specific customer" } }
                                   ]
                            }
                         }
}).params(request_timeout=3600).params(wait_for_completion=False).params(wait_for_active_shards=1).params(refresh=True)
response = update.execute()

```

The old and new field values can be provided by your python script.  
hope this helps
