It was news to me—but now the service is making moves to rectify the situation. Twitter has been rolling out a new search service that allows you to search for any tweet among the half-trillion that have been posted in its history.
Though the new Twitter search engine is limited to rather rudimentary keyword searches today, the company plans to expand into more complex queries in the months and years to come. And the foundational search infrastructure laid down by the company will help drive other Twitter tools as well. “It lets us power a lot more things down the road—not just search,” says Gilad Mishne, the Twitter engineering director who helped oversee the project.
