I'm currently trying to write a frontend using the REST API and would like to list some items based on a call to @querystring-search. As expected, the list of items returned does not include any related items on it as these are not returned with the brain. What would be the recommended best practise to include this information in the REST API call?
Additionally, what would be the current best-practise to extend the information returned by the above extended relations metadata, or from an @relations call? For example, if I have some custom fields on my related item and I want to avoid having to make additional REST API calls to get that information
