Building a complete Tweet index
Today, we are pleased to announce that Twitter now indexes every public Tweet since 2006. 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 em phasis on recency.
