Google and Caffeine : The Secret Link

1. A little over year ago ,Google unveiled a “secret project” of “next-generation architecture for Google’s web search“ which was supposed to include crawling, indexing, and ranking changes. While the biggest visible changes in Microsoft’s relaunched search engine, Bing, was user-interface related, Google’s secret project was supposed to be only infrastructure related and proposed no UI changes.

2. Thus after an year of the unveiling,Google is now getting faster and more comprehensive with a new Web indexing system called "Caffeine.As per the Google Blog Post's , the project now stands on completion stage and now "provides 50 percent fresher results for Web searches".

3. The old indexing architecture was based on several layers, some of which were refreshed at a faster rate than others; the main layer would get updated every couple of weeks.To refresh a layer of the old index, entire web was analysed, which meant there was a significant delay between when we found a page and made it available to the user. With Caffeine, the web is analysed in small portions and search index is updated on a continuous basis.Thus more improvement on existing setup....that I say "there is no end to improvement"
