It worked for a select group of toy problem domains and the answer for most high-concept searches would be noise or nothing.

The author never manages to convince me that the information they're looking for is on the Internet for Google to index in the first place. The author then asserts "don't just hit me with garbage," which is a fine assertion, except what they're interpreting as 'garbage' is the information other people making the search could actually use. Google A/B tested the hell out of "say nothing" vs. "guess something close to what the requester might care about" and the latter won out every time.
