We have a 3 node indexer cluster with one search head. We have allowed another team to connect their search head to our cluster so that they can pull certain statistics. Is there a way to restrict what they are allowed to search (namely disable real-time search ability)? We have control over our search head as far as what users can do, but we don't have any control over their search head configuration. We used to be able to restrict them when they connected via distributed search (needed a valid user/role on our end), but now that they are using clustering (only need the secret key to join) we don't have that option anymore.
