Is here a way to define which field will be used to sort search results? I’d like to, for instance, sort by release date, that way i can see all the (filtered) latest releases. Also it would be very useful to be able to see future releases.
That’s not really possible in the search. I recommend using the calendar page instead since that orders things by release date already.
You can open the advanced filters panel and specify a search term for the calendar, which should give you the results you’re looking for.
