Google New Search Index Method : Google Caffeine

Google announced the completion of a new web indexing system called Google Caffeine.
  • Google Caffeine provides 50% latest results for web searches than last index.
  • Google Caffeine is the largest collection of web content.¬†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.
  • Instead you’re searching Google’s index of the web which, like the list in the back of a book, helps you pinpoint exactly the information you need.

why did Google build a new search indexing system?

Content on the web is blossoming. It’s growing not just in size and numbers but with the advent of video, images, news and real-time updates, the average webpage is richer and more complex. In addition, people’s expectations for search are higher than they used to be. Searchers want to find the latest relevant content and publishers expect to be found the instant they publish.
