Editing Google Caffeine (section)

== Key Features ==
Google Caffeine introduced several key features that aimed to improve the speed, relevance, and comprehensiveness of Google's search results:

# Real-time indexing: With Caffeine, Google transitioned from a batch processing system to a system that allowed for continuous crawling and indexing of web pages. This enabled Google to index new pages and changes to existing pages much faster than before, reducing the latency between content creation and search visibility.
# Incremental indexing: Instead of recrawling and reindexing the entire web each time, Caffeine focused on indexing individual web pages in smaller chunks. This incremental approach allowed for faster updates to the search index and reduced the processing time required for indexing new content.
# Better scalability: Caffeine was designed to handle the ever-growing size of the web more effectively. It improved Google's ability to index large volumes of information quickly, ensuring that the search index stayed up to date with the rapid expansion of online content.
# Improved relevance: Caffeine's infrastructure update also aimed to enhance the relevance of search results. It improved Google's ability to analyze the relevance and quality of web pages by considering a wider range of factors beyond just page content, such as the freshness of information, the page's architecture, and the website's overall quality.
