The client throws several types of exceptions. All are under the namespace Manticoresearch\Exceptions.
Thrown when nodes fail with hard errors and no retries are left.
Soft errors returned by nodes. For example, when trying to insert a document with an ID that already exists or when trying to create an index that already exists.
