According to an internal Blog, Google today announced that it has rebuilt the search engine to deliver 50% fresher results from an even larger collection of Web content possible. This new ‘Caffeine’ index now captures real-time data, video and richer content. In a nutshell, ‘Caffeine’ is designed to continually index the Web. When information is updated, Caffeine will absorb the changes into the index.
Layered Index Vs Caffeine
Instead of updating its search database every night and making the new results available the next day, which is what it did previously, now, new search indexes will go live to deliver real-time search results within seconds. In the post on the official Google blog, software engineer Carrie Grimes wrote, “Caffeine provides 50 percent fresher results for web searches than our last index, and it’s the largest collection of web content we’ve offered. Whether it’s a news story, a blog or a forum post, you can now find links to relevant content much sooner after it is published than was possible ever before.”
P.S. It’s true. This post was indexed in 10 seconds. Impressive stuff.
