The amount of information that Caffeine is able to process is astounding. Never before has there been a search provider that could index in such a manner. The hardware is able to index hundreds of thousands of websites in parallel. In the past, due to the way Google indexed websites, it could take over a month for a page to be recognized by the algorithm. Now, Google is indexing a portion of the web ever day in order to find as much current information as possible. I am sure there are specific parts of the web that get indexed more regularly than others. Think MSNBC, FoxNews, CNN and so on. When people search “news” they probably want the most up to date page for their favorite news organization. Not a BBC article from 5 years ago. This is one of the reasons why Yahoo and Bing have to make many improvements if they want to be able to compete with Google after their merger.
Earlier Today, Google announced that they are implementing a major algorithm change. The major motivating factor behind the update is the Caffeine web indexing system that was implemented in June of last year. The Caffeine indexing system revolutionized the way Google could crawl and index new information placed on the web. Google often tried to make the comparison between an old 2 dimensional indexing system and the new 3 dimensional model. Caffeine strives to bring users the best search results as possible, and in many cases this also means the newest content possible.
