Introduction - New Google Indexing - Google Caffeine

What is New Google Caffeine Indexing?
The new Google indexing system, the tool scans all the pre-internet for the best answer to your question, promises "50% more current results in searches." His name is Caffeine. And he comes up with some impressive statistics from Google.

The main difference is that the system Caffeine, instead of searching an entire group of sites (represented as layers in the chart above) and then a group of lowest priority sites, and then another group less important, all with the algorithm of Caffeine is continuously indexed. Announced a few months ago, the Caffeine is to update missing Google to not lose ground to services like Twitter. And, of course, Google will have to maintain and continue to create innovations good not to lose his throne - our world is translated from analog to digital more and faster ways every day.

Now, the bizarre and frightening statistics Google:

• Every second, Caffeine processes hundreds of thousands of pages in parallel

• If it were a stack of paper, he would grow nearly 5 meters per second

• The Caffeine uses nearly 100 million gigabytes of storage in a database

• The Caffeine adds new information at a rate of hundreds of thousands of gigabytes per day

• You need 625 000 160 GB iPods to store as much information

• If these iPods are connected one by one, they would create a line of 64 km

How New Google Caffeine Indexing Works ?

Caffeine Web Indexing System . Users who do not make your living developed search engines as we must know that, when performing a Google search , not browsing the web in full, but the index that Google makes the Web. This rate is comparable to the list at the end of a book and allows us to locate exactly the information you need. (If you want to know how it works, .
You may wonder why we have developed a new system for search indexing . The contents of the Web continues to grow. In fact, not only increases the size and amount of content but also the richness and complexity means of the web pages with the introduction of videos, images, news and updates in real time. In addition, users now expect to get better results than before when searching. The objective of users is to find the latest relevant content, while publishers want to appear in search results immediately after publishing their content.
We have developed Caffeine to keep pace with developments in the Web and to meet the growing expectations of users. In the picture below you can see the differences in performance between our ancient system of indexing and Caffeine:

The old index was composed of several layers, some of which were updated faster than others. The main layer was updated every two weeks. To update an old index layer was necessary to analyze the entire Web. For this reason, considerable time passed since we found a page until the user could access it.
Caffeine allows us to analyze the Web in small portions and update the search index on a continuous and comprehensive . We can add new pages to the index published or new information in existing pages as soon as we find them. This allows you to find more recent information, regardless of when and where it is published.
Caffeine allows us to very large scale indexing of . In fact, this system processes hundreds of thousands of pages simultaneously every second. If apilásemos these pages as sheets of paper, the mountain would increase at a rate greater than 5,000 meters per second. In each database Caffeine is stored almost 100 million gigabytes of data and information is growing at a rate of hundreds of thousands of gigabytes per day. It would take 625,000 high capacity iPods to store this much information, so many that, if placed in rows next to each other, would cover a distance exceeding 64 kilometers.

worth mentioning that to do a search on any search engine , it does not search the entire site but in its own index of websites. Therefore, "to keep pace with the evolution of the Internet and meet the increasingly high expectations users, we decided to create Caffeine, "said Carrie Grimes, Google software engineer. "Our old index had several layers, some of which were upgraded to a faster pace than others, and the main layer was updated every couple of weeks . To update a layer of the old index, we analyzed the entire network, which obviously amounted to a significant delay between the time we found the page and the time when we put available to users , "Grimes admitted. Thanks to Caffeine, Google "as they find new pages or new information in existing pages" may "add that data directly to the index. This means that users can find the latest information, as never before, no matter when or where it was published "he told the company on his blog . Watch Video :
