# facetingAfterDistinct

> Whether facet counts are computed after applying the distinct setting

export const Setting = ({type, default: defaultValue, defaultNote, scope, min, max, formerly}) => {
  const renderedDefault = defaultValue === '' ? '""' : defaultValue;
  const renderedNote = defaultNote ? `(${defaultNote})` : '';
  return <ul>
      <li><strong>Type:</strong> <code>{type}</code></li>
      <li><strong>Default:</strong> <code>{renderedDefault}</code>{renderedNote}</li>
      {min && <li><strong>Min:</strong> <code>{min}</code></li>}
      {max && <li><strong>Max:</strong> <code>{max}</code></li>}
      <li><strong>Scope:</strong> <a href="/doc/api-reference/api-parameters"><code>{scope}</code></a></li>
      {formerly && <li>
          <strong>Deprecated name:</strong> <code>{formerly}</code>
        </li>}
    </ul>;
};

<Setting type="boolean" default="false" scope="search" />

By default, Algolia calculates facet counts **before** applying the [`distinct`](/doc/api-reference/api-parameters/distinct) setting.
This can lead to higher facet counts than expected.

When `facetingAfterDistinct` is `true`,
facet counts are computed **after** applying `distinct`,
giving counts based only on distinct records.

## Usage

* Applies to **all** facet attributes.
* To apply this behavior selectively, use the [`afterDistinct`](/doc/api-reference/api-parameters/attributesForFaceting#param-after-distinct) modifier in `attributesForFaceting`.
* If both `facetingAfterDistinct` and `afterDistinct` are used, `facetingAfterDistinct` overrides the attribute-level setting.
* Only use this setting if **all records sharing the same distinct key have identical facet values**—otherwise facet counts may appear inconsistent.
