Delete indices

Indices with replicas

If the index you want to delete is a replica of another index, you must first unlink it.

If the index is a primary index and has replicas, the replica indices will become independent indices if you delete their primary index.

Delete indices in the Algolia dashboard

To delete an index from the dashboard:

Go to the Algolia dashboard and select your Algolia application.
On the left sidebar, select Search.
Select your Algolia index:
Select Manage index > Delete.
Type DELETE to confirm and click Delete.

Delete indices with the API

To delete an index, use one of these methods:

API clients: deleteIndex
Algolia CLI: algolia indices delete

Delete multiple indices

To delete more than one index:

Use listIndices (API client) or algolia indices list (Algolia CLI) to get your indices
Use multipleBatch or algolia indices delete to delete multiple indices with a single request.

To delete replica indices, you must first delete their primary indices.

Clear records from an index in the Algolia dashboard

If you only want to delete (clear) the records from an index, keeping the index configuration, follow these steps:

Go to the Algolia dashboard and select your Algolia application.
On the left sidebar, select Search.
Select your Algolia index:
Select Manage index > Clear.
Type CLEAR to confirm and click Clear.

Clear records from an index with the API

To remove only the records from the index, while keeping the settings, synonyms, and rules, use one of the following methods:

API clients: clearObjects
Algolia CLI: algolia indices clear
