For example, I'm searching form "men's ultralight running socks". Several of the first things listed are "cushioned" socks, which are the opposite of what I want. On eBay, if I search for "men's ultralight running socks" that's exactly what I get. No more, no less. Amazon's algorithm throws in so many adjacent items that sometimes it's hard to search for something very specific. There are plenty of things that annoy me about eBay, but their searching is way better.
