Wordpress "Custom Post Category Facets"

Hi there. I use the wordpress Plugin (newest version) and everything seems to work great. Now I would like to setup everything in a way to make the search results even better for my users.

I use plugins for my content that have “custom posts” that have their own category-system. I would like to setup a filtering-system to define search results within those categories and subcategories. Comparable to
amazon (see screenshot for what i mean please). Can you tell me on how
to set this up?
