Has anyone got an efficient way to fetch random nodes? The way I'm doing it now is to fetch nodes and pipe it through to the shuffle operator. It works, sure, but often I end fetching ALOT more nodes than I actually need. Is there a simple way to select only the desired amount of nodes randomly from the database directly? Do I have to create som custom filter for this?
