A History of Facebook's New Search Engine
For years now, Facebook watchers have wondered when the company would unleash the potential of its underpowered search bar. (Nobody has feared this day more than Google, which suddenly faces a competitor able to index tons of data that Google’s own search engine can’t access.) They have also wondered how a Facebook search product might work. Now we know. Graph Search is fundamentally different from web search. Instead of a Google-like effort to help users find answers from a stitched-together corpus of all the world’s information, Facebook is helping them tap its vast, monolithic database to make better use of their “social graph,” the term Zuckerberg uses to describe the network of one’s relationships with friends, acquaintances, favorite celebrities, and preferred brands.
“There’s no real way to cut through the contents of what people are sharing, to fulfill big human needs about discovery, to find people you wouldn’t otherwise be connected with,” Zuckerberg told Levy. “And we thought we should do something about that. We’re the only service in the world that can do that.”
