+//
+// Please note that it's not acceptable to have both OwnerID and RepoID to be non-zero,
+// or it will be complicated to find secrets belonging to a specific owner.
+// For example, conditions like `OwnerID = 1` will also return secret {OwnerID: 1, RepoID: 1},
+// but it's a repo level secret, not an org/user level secret.
+// To avoid this, make it clear with {OwnerID: 0, RepoID: 1} for repo level secrets.
+//
+// Please note that it's not acceptable to have both OwnerID and RepoID to zero, global secrets are not supported.
+// It's for security reasons, admin may be not aware of that the secrets could be stolen by any user when setting them as global.
