- **Type:** `list<string>`
- **Default:** `[]` (no excluded attributes)
- **Scope:** [`settings`](/content/doc/api-reference/api-parameters/index.html)

The `unretrievableAttributes` setting specifies attributes in your records to exclude from search results. This can help protect sensitive information, such as internal metrics or access controls, which may be used for ranking or filtering but shouldn’t be visible to end users.

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

## Usage

- Attribute names are case-sensitive.
- This setting is ignored if the query is authenticated with the **Admin API key**.
