I looked through the indoor volleyball rulebook, and can't find anything on this in there, through Google, nor in any previously asked questions here.
I was told many times before that you cannot purposely set a ball over the net unless your back or front are parallel to the net, as in you can only set it forward or backwards, not to the side. However, I was watching some indoor volleyball highlights and a girl did a purposeful low side set over the net for a point.
What is the official rule? I'm referring to indoor volleyball (recreational/intermediate leagues, not like college or anything) and I would like to know the official ruling.
Edit: to be clear, in case it matters, I'm referring specifically to the 2nd hit.
