If you're using Elastic then it's inefficient and discouraged to allow accessing random pages (ex. requesting page 100 before having visited pages 1-99). I.e. this could be a technical limitation and there aren't use-cases that require accessing those pages arbitrarily. For Shodan, we allow random access for the first 10 pages but if you want to go beyond that then you need to go in order so we can use a search cursor on the backend to more efficiently go through the results.
