<Setting type="list<string>" default="[]" scope="settings,search" formerly="disableTypoToleranceOn" />

The `disableTypoToleranceOnAttributes` parameter lets you turn **off typo tolerance**
for specific attributes, which must be a subset of the
[`searchableAttributes`](/doc/api-reference/api-parameters/searchableAttributes) index setting.

This means that a user query must match those attributes **exactly**, without spelling corrections.

## Usage

This setting is useful when:

* **Precision is critical.** For example, searching for product SKUs, phone numbers,
  or [hyphenated attributes](/doc/guides/managing-results/optimize-search-results/typo-tolerance/how-to/how-to-search-in-hyphenated-attributes#hyphenated-attributes-need-to-match-without-typos)

* **You want to reduce irrelevant matches** in long-form text fields like `description` or user-generated content.
  Combining this with [`disablePrefixOnAttributes`](/doc/api-reference/api-parameters/disablePrefixOnAttributes) helps narrow down fuzzy matches.

Use caution in these cases:

* **Proper nouns or intentionally misspelled titles**, such as movie names or creative brand names.
  Instead, use [`disableTypoToleranceOnWords`](/doc/api-reference/api-parameters/disableTypoToleranceOnWords) or add [synonyms](/doc/guides/managing-results/optimize-search-results/adding-synonyms).

* **Named entities** like people or places that might be hard to spell.
  In these cases, increasing [typo tolerance](/doc/guides/managing-results/optimize-search-results/typo-tolerance/in-depth/configuring-typo-tolerance)
  can be more helpful.

<Info>
  There's no hard limit on the number of attributes 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.
