Great question! I wonder if the website shares that data publicly— is that common I wonder— sharing “traffic data” — sorry if this is the wrong term. I will get back to you if I find an answer.

Explored the website this morning— so many gems including sci-fi stories. I did not find an answer to your question— they offer a contact email— maybe something to discover this route. The menu is very helpful— it’s a fantastic website— very organized. Not sure about a filtered search bar though.
