I'm getting a 'One or more indexers are invalid. Make sure your Magento cron job is running.' and it seems I need to run php bin/magento indexer:reindex from the CLI. I get the index rebuilt successfully on all indexes but one the Catalog Search This is the Command along with the full success and error message.
