                        "_source": false
                    }
                  }
                }
              }
            }
          ]
        }
      }
    }
  }
}

```

Top score is zero, nothing matches. Can we not use those fields which are excluded from `_source` in scrip score?

From our [scripting docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting-fields.html#_search_and_aggregation_scripts):

Field values can be accessed from a script using [doc-values](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting-fields.html#modules-scripting-doc-vals), [the `_source` field](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting-fields.html#modules-scripting-source), or [stored fields](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-scripting-fields.html#modules-scripting-stored).
