The popular micro-blogging service Twitter yesterday announced that it's finally indexed every tweet, allowing anyone on Twitter to find any public tweet sent since 2006.
Advanced search is now available on the web and mobile, but not in third-party Twitter clients. Once the company opens up the Search API to developers, apps that analyze and map search terms over time will get better.
The biggest benefit of searching through Twitter's public archive: no longer do you have to download your entire Twitter archive periodically just to be able to re-visit your old tweets. Before, Twitter search was limited to tweets from the past couple of weeks.
Noting it's always been its long-standing goal to let people search through every tweet ever published, Twitter shared a number of technical details on the kind of search index infrastructure needed to make the feature a reality, a considerable feat given users have published hundreds of billions of tweets since the first tweet went live over 8 years ago.
