Twitter has announced via its engineering blog that it’s making its entire public tweet archive searchable to everyone. Previously it had only made the archive accessible to select partners.

Twitter’s search engine will index roughly half a trillion tweets, including every public Tweet since 2006. The move means historic tweets will now be accessible to everyone through Twitter’s public search.
