The Next Frontier for Search Engines

I think right now we have to do a tremendous amount of work to try and translate these questions into text that we would issue to a search engine. And I think that's really the next frontier for us is how do we on the query side help users just naturally intuitively express whatever information need they have. How do we understand the whole universe of information, not just the web pages, but all the images and video and audio out there and take that next level of like concept understanding to match those together so that we can get users even more precise answers that really help them.
