By the way `"script": "doc['mygroup'].values....` \< i think I cannot use `doc` here. It should be `"script": "_source['mygroup'].values` per [ElasticSearch: access document nested value in groovy script](https://discuss.elastic.co/t/elasticsearch-access-document-nested-value-in-groovy-script/21644) ? Please let me knwo what do you think @nik9000
