Google announces the full release of Caffeine
Google has finally rolled out Caffeine, a brand new version of its web indexing system. Announced just under a year ago, the arrival of the new system has been highly anticipated and is designed to generally improve the speed and relevance of search results by utilising a more comprehensive, and continuously updated, index.
Officially announced on the Google blog, Caffeine is now live and demonstrates a complete change to the infrastructure of the search engine. Where the previous index was constructed of layers which would update at different times, with each update requiring a full scan of the entire web, Caffeine analyses the web in smaller sections and is therefore capable of updating its servers continuously.
