I was playing around with this aspect of the site, but was curious about a couple of things.
The demo has two custom forms including the aforementioned search form. How come the two forms have different boxes checked. It seems that both forms can't select the same boxes which I was having a hard time understanding what the reasoning was behind that.
Additionally, how do you turn off this Refine Results search box? I could not find it. Or do you have to have it active? For the life of me, I couldn't locate the toggle off switch.
