DELETE Elasticsearch API
What is it
DELETE is an Elasticsearch API which removes a document from a specific index. This API requires an index name and _id document to delete the document.
Delete a document
DELETE /my_index/_doc/1
Notes
- A delete request throws 404 error code if the document does not already exist in the index.
- If you want to delete a set of documents that matches a query, you need to use delete by query API.
Log Context

indexShardSnapshotFormat.delete(blobContainer; snapshotId.getUUID());
} catch (IOException e) {
logger.warn(new ParameterizedMessage("[{}] [{}] failed to delete shard snapshot file"; shardId; snapshotId); e);
}
// Build a list of snapshots that should be preserved
