"We recently added some new features to Google. The most significant is a summary for each result that highlights where your query matched. This makes for a much more informative summary than most search engines provide. You can actually see where your query matched without having to download each page.
Also, you can fetch contents from our repository by clicking on the "Cached" link near each result. This often is faster than going to the original, but of course can give you outdated information since it is based on our last crawl. This feature can be very useful if the original is not available or the network is down, you will still have access to the page (but not the images)."
