Changing Column number for Woocommerce Archive/Search Results

Hi, Great theme by the way, it is a real pleasure to work with. Ok, so my main issue is this. It is easy to change how many columns of products show on the products pages. But when you search it defaults to the 3 column grid. I can’t find anywhere to change that. I would like to make it 5 columns like the rest. Is there a solution for this?

One other question, this may be a woocommerce thing. But when I add the Woocommerce Search Widget to the sidebar, it doesn’t let me search via product tags. Do you know of a way to make this happen?

Thanks!
