 As the name suggests, the multi-search operation lets you bundle multiple search requests into a single request. OpenSearch then executes the searches in parallel, so you get back the response more quickly compared to sending one request per search. OpenSearch executes each search independently, so the failure of one doesn't affect the others.

 A task is any operation you run in a cluster. For example, searching your data collection of books for a title or author name is a task. When you run OpenSearch, a task is automatically created to monitor your cluster's health and performance. For more information about all of the tasks currently executing in your cluster, you can use the `tasks` API operation.

 The `append` processor is used to add values to a field:

 - If the field does not exist, the `append` processor creates an array with the specified values.

 The following is the syntax for the `append` processor:
