Thanks for checking in @roisinkirby - I was not able to figure any of those things out. I decided to give the Hubspot search some more time to mature and went back to our paid search tool, Sajari. It gives me most of the controls mentioned in my original post, and since I already had it set up, I figured I can afford to wait for the Hubspot search to get a few more features under its belt before I move to it.
