Multi_match search

Elastic Stack Elasticsearch
1

Hi:
I have setup a field as a multi-field. and I execute a search like so :

POST test_autosuggest_v2/_search
{
"size": 20,
"query": {
"bool": {
"must": [
{"multi_match": {
"query": "andrea smith",
"fields": ["name","name.autocomplete","name.na","name.shingle"],
"type": "best_fields"
}

    }
  ],
  "filter": {
    "term": {
      "type": "judge"
    }
  }
}

}
}

Is it possible to know which field was the biggest contributor to the score ?
I would like to know if there was an exact match to my query term. if not an exact match, I would like to know which field contributes most to the score.

is this possible ?
