# Score context
Use a Painless script in a [function score](https://www.elastic.co/elastic/docs-builder/docs/2773/reference/query-languages/query-dsl/query-dsl-function-score-query) to apply a new score to documents returned from a query.
For help debugging errors in this context, refer to [Debug script score calculation errors in Painless](https://docs-v3-preview.elastic.dev/elastic/docs-builder/docs/2773/explore-analyze/scripting/painless-script-score-calculation-errors).

## Variables

<definitions>
  <definition term="params (Map, read-only)">
    User-defined parameters passed in as part of the query.
  </definition>
  <definition term="doc (Map, read-only)">
    Contains the fields of the current document. For single-valued fields, the value can be accessed via `doc['fieldname'].value`. For multi-valued fields, this returns the first value; other values can be accessed via `doc['fieldname'].get(index)`
  </definition>
  <definition term="_score (double read-only)">
    The similarity score of the current document.
  </definition>
</definitions>


## Return

<definitions>
  <definition term="double">
    The score for the current document.
  </definition>
</definitions>


## API

Both the standard [Painless API](https://www.elastic.co/guide/en/elasticsearch/painless/current/painless-api-reference-shared.html) and specialized [Field API](https://www.elastic.co/guide/en/elasticsearch/painless/current/painless-api-reference-field.html) are available.

## Example

To run the example, first [install the eCommerce sample data](/elastic/docs-builder/docs/2773/reference/scripting-languages/painless/painless-context-examples#painless-sample-data-install).
The following request boosts results for customers in New York, helping highlight local preferences or regional inventory. It uses a `function_score` query to match products with "jeans" in the name and increase their score when the city is New York.
```json
GET kibana_sample_data_ecommerce/_search
{
  "query": {
    "function_score": {
      "query": {
        "match": {
          "products.product_name": "jeans"
        }
      },
      "script_score": {
        "script": {
          "source": """
            double baseScore = _score;
            def city = doc['geoip.city_name'];

            if (city.size() > 0 && city.value == 'New York') {
              baseScore *= 1.5;
            }

            return baseScore;
          """
        }
      }
    }
  }
}                        
```
