Display keyword search facet in custom region + price range facet for solr

Hi,

I'm wondering how I can achieve the functionality seen on http://www.etcwineshops.com/shop-here. I also want to display the keyword search form (= search box facet) in the same region my other facets are displayed, but I can't figure out how to do this?
I'm also working with Drupal Commerce and want to display a price range facet. Are there any extra modules required to create a range facet for commerce product prices?

Thanks!
