Since that first simple Tweet over eight years ago, hundreds of billions of Tweets have captured everyday human experiences and major historical events. Our search engine excelled at surfacing breaking news and events in real time, and our search index infrastructure reflected this strong emphasis on recency. But our long-standing goal has been to let people search through every Tweet ever published.
This new infrastructure enables many use cases, providing comprehensive results for entire TV and sports seasons, conferences (#TEDGlobal), industry discussions (#MobilePayments), places, businesses and long-lived hashtag conversations across topics, such as #JapanEarthquake, #Election2012, #ScotlandDecides, #HongKong, #Ferguson and many more. This change will be rolling out to users over the next few days.Twitter Now Indexes Every Public Tweet Since 2006 [blog.twitter.com]
For now, complete results from the full index will appear in the “All” tab of search results on the Twitter web client and Twitter for iOS & Twitter for Android apps. Over time, you’ll see more Tweets from this index appearing in the “Top” tab of search results and in new product experiences powered by this index.
