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.
