mUpdate #

Updates multiple documents.

Conflicts may occur if the same document gets updated multiple times within a short timespan in a database cluster.

You can set the retryOnConflict optional argument (with a retry count), to tell Kuzzle to retry the failing updates the specified amount of times before rejecting the request with an error.
