Searchable blog database?

I’m trying to figure out a way to create something like this through WordPress. Whether it uses Custom Fields or whatever, I’d like to create a database for my website that has product specifications that the user can search for with multiple selections. I could use Tags if I just wanted them to be able to look for one attribute, but I’d like for them to have a full range of options like the camera database on that page… is this possible with WordPress? I’d really appreciate any help, even if it’s a nudge in a completely different direction. Thanks!
