Google has initiate a novel Web indexing system to offer client with more up-to-date search results, the corporation said.

The novel system, called Caffeine, delivers results that are closer to "live" than Google's preceding system, the corporation said.

Before, Google would edge a division of Web each night, index it and shove it out in its consequences. With Caffeine, as Google edge Web and finds novel information, it indexes it instantly.

"We process it instantly so we can serve it seconds shortly," said Matt Cutts, the head of Google's web spam team. He reveals the news at the Search Marketing Expo in Seattle.

When Google started, it would update its index merely every four months, he said.

Approximately 2000, it started indexing every month in a process that took a week to 10 days. "The humorous thing is, we didn't have sufficient ability to update all our data centers at once," he said. That intended the people may get different consequences when searching for the same term if they were striking different Google data centers.

Caffeine went live "in the previous few days" and is at present being used in all Google data centers, he said.

In addition to portion "fresher" results, Caffeine "particularly augment our capability to scale up," Cutts said. The corporation will be able to index many more documents "on the order of 100 petabytes," he said.
