On Atlantic you still had so many SoTs of a single skill that this returned only an error (back before I completely stopped selling SoTs out of frustration over this). I'm pretty sure you didn't try that on Atlantic. SoTs were my main thing for quite a while, but pricing them became a constant PITA with VS bailing out on 90% of the searches.
Maybe it's better these days, but I rather doubt it.
E: I gave it a quick try and indeed all queries worked and gave results. That's cool news. I will give it another shot later when the Americans are awake and the shard is a bit more busy
On the flipside, there were not many SoTs available at all, let alone 5.0s. Barely two pages for skills like taming or magery
