Google search promises to get fresh with you

After weathering some less than enthusiastic receptions to Gmail and Google Reader revamps, not to mention the long awaited launch of a Gmail app for the iPhone, the Google upgrade train just keeps on rolling along. This time out, Mountain View is targeting its real bread and butter: search. Google is harnessing its Caffeine indexing system to offer up fresher results -- a change that will apparently affect around 35 percent of the site's searches. The new results include more up to the minute results, prioritization for recent happenings and more frequent updates.
