Queries the information about shards that are being restored or shards that are restored. By default, this operation returns only the information about shards that are being restored after you call this operation.

Note Shard restoration is the process of synchronizing from a primary shard to a secondary shard. After the restoration is complete, the secondary shards are available for search.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
