Search for a model group

When you search for a model group, only those model groups to which you have access will be returned. For example, for a match all query, model groups that will be returned are:

• All public model groups in the index
• Private model groups for which you are the owner
• Model groups that share at least one of the backend_roles with you

For more information, see Model access control.
