John Battelle wrote an entry the other day named Snap Does Suggest One Better. In that entry, John discusses how Snap is a much more advanced Google Suggest. Bill Gross, founder of Snap, told John;
Google suggest is awesome, but doesn’t do substrings, just the leading characters of the search term, I believe. Also, Google shows you hit count in the index, not number of searches performed by users. Number of searches by users seems to yield useful results from the “network” of people in a collaborative filtering kind of way. Just try typing in, say PASADENA, or SOLAR ENERGY, or anything, and watch what a relevant list you get because it’s using the collective knowledge of the whole network!
Pretty cool stuff. Check it out yourself at Snap.com. Forum discussion at Cre8asite Forums.
