# exactOnSingleWordQuery

> How the Exact ranking criterion is applied to single-word queries

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>

};

<Setting type="enum<string>" default="attribute" scope="settings,search" formerly="enableExactOnSingleWordQuery, useQueryEqualsOneAttributeInRanking" />

The `exactOnSingleWordQuery` parameter controls how the [Exact ranking criterion](/doc/guides/managing-results/relevance-overview/in-depth/ranking-criteria#exact) is evaluated when the query contains only one word.

## Options

<ParamField path="attribute">
  The Exact criterion is applied when the query exactly matches the entire value of an attribute.
</ParamField>

<ParamField path="none">
  The Exact ranking criterion is ignored on single-word queries.
</ParamField>

<ParamField path="word">
  The Exact criterion is applied when the query word is found exactly in the record.
  The word must be at least three characters long and must not be a stop word.
  Only exact matches will be highlighted. Partial or prefix matches will not be.

  <Info>
    By default, Algolia matches query terms at the **beginning of words** in your records (prefix matching). For alternatives, see [Match queries in the middle or end of words](/doc/guides/managing-results/optimize-search-results/override-search-engine-defaults/how-to/how-can-i-make-queries-within-the-middle-of-a-word).
