Google's New Search Index Process: Caffeine

A new web indexing system named Caffeine. Google announced that Caffeine is ready to work. Caffeine provides 50% fresher results for web searches. Google's old index had several layers, some of the layer revived at a faster than the other layers. To revive a layer of the old index, Google would study the entire web. It means that there is interruption between when Google found a page and made it on hand to the users. Caffeine can evaluate the web in small portions and revise search index on a constant basis, worldwide. As Google find new pages, or new information on existing pages, Google can add these straight to the index. That means we can discover fresher information sooner than before—no issue when or where it was available.
