Google has released its Caffeine indexing technology. As the most significant change Google has made to the basic technology that crawls the Internet and ranks Web pages since 2006, Caffeine has been in the testing phase for almost a year. According to Google, "Caffeine provides 50 percent fresher results for web searches than our last index, and it's the largest collection of web content we've offered."

In a blog post announcing the completion of Caffeine, Google

Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.

With Caffeine, we analyze the web in small portions and update our search index on a continuous basis, globally. As we find new pages, or new information on existing pages, we can add these straight to the index. That means you can find fresher information than ever before—no matter when or where it was published.

Grimes pointed out that every second Caffeine processes hundreds of thousands of pages in parallel. To put this in perspective, Google says, "Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day. You would need 625,000 of the largest iPods to store that much information; if these were stacked end-to-end they would go for more than 40 miles."

Why is google copying search UI from bing??? 1st they had the "Search Results" page display frames like the BING, not the main page started sporting changeable wallpapers!! What is going on??? Google, people are really not stupid and they can see. Copying styles is a serious turn off!!

Copying styles doesn't really matter to me as long as it enhances my search experience. If Microsoft has a beef with it, I'm sure a lawsuit will follow soon enough. I haven't seen the wallpapers on my iGoogle page though.

This is actually pretty cool. I have noticed quite a few times that when breaking news is happening you can't find it on google for a while.

Also the background was not a Bing original. Ask was doing it years before bing copied it and now google.

I don't particularly care for them adding backgrounds to the Google homepage but I'm more accustomed to the white on black homepage. Again, I don't care if it's copied, I care about my search experience.

Bout to say the same for you Rapid:)

I though both of you were to busy playing AVP or STrek online with your HH rigs.

Maybe that is a good idea for the groups section, list the online games with our screen names?

I haven't noticed Googles new setup within my default search engine. When they decide to change that to make it look like Bing is the day that I go ahead and switch over.

@TaylorKarras: I completely agree. Google has been adding more and more scripts and flashy garbage to what was once a pristine-- and small-- web page. When I want to search for something, I want to see what I'm searching for-- not a picture of some sort of tree-covered island. (Hey, it must really amuse people who're using wireless and paying by the megabyte!)

I've lately been using the workaround to go to instead of but that isn't perfect; you lose the (wait for it to fade in) search type bar, so you have to adapt if you want to search for shopping or image results. Of course, if I stayed logged in to Google, feeding them consumer information (what, you think programmers work on Chrome out of a love for the interface?) I could turn off the pictures... but I almost always close the browser window when I'm not actually working on the Web, meaning that every time I open Firefox, Google launches with a background image.

I still like them, but that like is taking some hits.


EDIT: And we're back. Google has removed default images, so they've gone from Art Nouveau to Bauhaus.
