I want to create a better searching experience for my customers in the product catalog.  We have thousands of products and our users want to be able to filter search results.  Like on cars.com for example, users can click a checkbox to show just Trucks and another checkbox for just Toyotas, etc. filtering the results down to just what they want to see.  I don't find this capability in SF Product Catalog.  Am I missing something or do we have to code this?
