After lots of research and months of testing, finally Google is ready to serve its billions of users worldwide with a hot and steaming cup of Caffeine by rolling out its new web indexing system. As we all know that web indexing is at the heart of all search engines which means none can work without it but if it’s as good as Google’s then success is not far.
Recently Microsoft had also debuted Bing, which used to employ an indexing system that was rewritten form of the old MSN Search. The indexing service till date has received positive reviews and thus was embraced by Yahoo for its search engine, making it the world’s second largest player in the Search market.
Google, as ever holds the first and an extremely dominant place in the search market, was working for making major modifications to improve the search results and finally after months of hard work, last month it rolled out the major modifications it made which also includes changes to the page layout which shows search results. With these new changes Google promises “50 percent fresher results for web searches” as compared to the results that were found with its last indexing service.
In its blog, Google explained the need for Caffeine, “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.”
The blog post also details the astonishing abilities of the new indexing service, stating, “Caffeine lets us index web pages on an enormous scale. In fact, every second Caffeine processes hundreds of thousands of pages in parallel. If this were a pile of paper it would grow three miles taller every second. Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day. You would need 625,000 of the largest iPods to store that much information; if these were stacked end-to-end they would go for more than 40 miles.”
