Google has bought the rights for a search algorithm developed by Ori Allon, a student at the University of New South Wales in Australia. The Age reports that Rob Pike, who is a Google engineer, was very excited about the algorithm. "This is the first time I've walked out and said: 'Wow! We should buy this stuff'. So it's pretty unique".
Orion's algorithm displays an extended snippet from each result, so you don't have to visit the site to get the answer you need.
Eric Schmidt told in a interview that Google will make "heavy, heavy investment in new search algorithms" to improve the quality of Google search.
Google still didn't decide if they integrate Orion's algorithm in their web search or they release it as a new product.
