New content may start finding its way onto Google quicker all of a sudden. The search company says it has completed work on Caffeine, a brand-new indexing system that purportedly delivers "50 percent fresher results" compared to the previous scheme. Google provides this simplified description in its announcement blog post:
Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.
With Caffeine, we analyze the web in small portions and update our search index on a continuous basis, globally. As we find new pages, or new information on existing pages, we can add these straight to the index. That means you can find fresher information than ever before—no matter when or where it was published.
Want some numbers? Google says Caffeine runs through "hundreds of thousands of pages in parallel," with an index that consumes up 100,000 terabytes of storage and grows by hundreds of thousands of gigs each day.
The firm adds that Caffeine will pave the way for further performance improvements, as well. Users can purportedly expect to see those improvements "in the months to come."
