"Functional websites" is not what we are discussing here, but amazing websites.

I've seen a carparts store online and it had something really similar, a few words like "oil filter 2017 ford mustang" and you were literally looking at the part in the dropdown list, exactly what you want.

What do most sites do wrong?

1) Not loading the search data into RAM on the server so it is really fast - most companies could do this with their level of stock and only need a couple of GB per web server 2) Requiring a postback to start filtering 3) Not allowing the ordering of search terms to be changed e.g. "Ford Mustang Oil Filter" should match the same as "Oil Filter Ford Mustang" 4) Not having images for all results 5) Not being able to zoom in on images to check something is what you think it is 6) Using a stock image which doesn't necessarily match the item

For companies whose primary interface with the public is searching for stuff, most e-commerce sites I use are shamefully bad at both performance and usability.

Kudos to Mcmaster!
