# disableTypoToleranceOnWords

> List of words which require exact matches

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="list<string>" default="[]" scope="settings" />

The `disableTypoToleranceOnWords` parameter lists words that must **match exactly** in search queries.

This is useful for **acronyms** like `"PHP"`, `"MySQL"`, `"MAMP"`.

[Splitting and concatenation](/doc/guides/managing-results/optimize-search-results/handling-natural-languages-nlp/in-depth/splitting-and-concatenation) are also turned off for the specified words.

<Info>
  There's no hard limit on the number of words you can include,
  but adding too many can slow down [`getSettings`](/doc/rest-api/search/get-settings) operations
  and degrade performance in the Algolia dashboard.
