ISO a dynamic post search and sorting plugin for Wordpress

I am making a site that has a high focus on content discovery (but is not a marketplace) and so a fun and engaging sorting tool is really important!

I am looking for a wordpress plugin (but if you know of a theme that would do the trick I would be interested to take a look at that to!) that has good custom search that includes customizable fields, drop downs and or buttons and is responsive/ dynamic. I really like the way this site lays things out and behaves: Anyone have any ideas where to look for something like this?

I am not sure I am using the correct terms to describe what I am looking for, because most of my searches have not turned up much like the link above, so please ask questions if I am not clear :slight_smile: Thanks!
