Search for a model

Use this command to search for models you've already created.

The response will contain only those model versions to which you have access. For example, if you send a match all query, model versions for the following model group types will be returned:

• All public model groups in the index.
• Private model groups for which you are the model owner.
• Model groups that share at least one backend role with your backend roles.
