Twitter Announces New Search Architecture 
By: Doug Caverly 2010-10-07 The 2011 Ford Mustang represents a vast improvement over the 2010 car; it's better to the point that the 2011 V6 is almost as fast as the 2010 V8. But the different vehicles look almost identical, and it's in a similar manner that Twitter's search engine was recently upgraded in a big way.
Twitter announced late yesterday that it's been implementing a new search architecture, as opposed to a fresh search interface, over the past few weeks. And the company tried to avoid downtime or anything else that would tip users off to the change. As for what's different, engineer Michael Busch wrote on the Twitter Blog, "We estimate that we're only using about 5% of the available backend resources, which means we have a lot of headroom. Our new indexer could also index roughly 50 times more Tweets per second than we currently get! And the new system runs extremely smoothly, without any major problems or instabilities (knock on wood)." Then Busch added, "But you might wonder: Fine, it's faster, and you guys can scale it longer, but will there be any benefits for the users? The answer is definitely yes! The first difference you might notice is the bigger index, which is now twice as long - without making searches any slower. And, maybe most importantly, the new system is extremely versatile and extensible, which will allow us to build cool new features faster and better." So keep an eye out for additional upgrades, since Twitter now seems to have lots of freedom to experiment. Enjoy the absence of the fail whale, too, for as long as that lasts.
