I think it depends how specific your buying is.
If I'm searching for Scooter, it may be good that it returns also mopeds and motorcycles.
But if I'm searching for Nikon d850, and get first 10 entries for Nikon d750, Nikon d610, canon 5dMkii, Sony rx100, and then finally a d850, then its really really annoying; and that's 80 percent of my experience.
For the other 20 percent, When I do want to search for something generic like bicycle or synthesizer, I frequently want to see new entries since the last time I searched - I don't want to see same synthesizer (or heat pump dryer:) day after day after day. Instead, Facebook's fuzzy algorithm fill cheerfully show me what it thinks is the best answer day after day and week after week, even though its a crappy casio that shouldn't even be listed as a synthesizer and it's been there for 7 weeks and is actually sold; it will refuse to show me chronological list so I can see what's new and added. It will then cheerfully ignore geographic distance and get me excited about something 4 hrs away.
So for me at least it's a lose lose scenario - our experiences clearly differ radically, and it may be simply down to how specific of a thing we want to. I typically want something specific, and if I want generic, then I'd like a category please, something which Facebook also sucks at as others have pointed out :).
(and I lied in my example to give FB a chance... In reality shen I search for "scooter" , I get motor scooters, electric scooters, the Segway wannabes, and six other types of things I don't want, so even then fuzzy search fails me :)
