Aggregation with significant_text on wildcard fields

Elastic Stack Elasticsearch

Hi, everyone
I have query below

GET contract/_search
{
    "query": {
        "bool": {
            "should": [
                {
                    "query_string": {
                    "fields": [
                        "contract*_content"
                    ],
                    "query": "company1"
                    }
                },
                {
                    "query_string": {
                    "fields": [
                        "contract*_content"
                    ],
                    "query": "keyword1"
                    }
                }
            ]
        }
    },
    "aggregations": {
        "my_sample": {
            "sampler": {
                "shard_size": 1000
            },
            "aggregations": {
                "keywords": {
                    "significant_text": { "field": "contract*_content"}
                }
            }
        }
    }
}

This throws an error since field contract*_content doesn't exist.
If I change it to contract1_content, contract2_content, respectively, and so on. it will work, but it only get significant keywords on the specified field.

Is there any workaround to get it done to aggregate with significant_text on wildcard fields?

Thanks,
Newman

No, there is no wildcard support in field names but multiple significant text aggregations can be stacked under the same sampler aggregation.
