Multi_match search

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.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 ?
