Twitter is letting its users look at every tweet made since the company's birth in 2006 in its most recent update.

The new features works similar to one the social network introduced in 2012 that lets you download your personal library of tweets, in that this one lets you search for any tweet from any user during their time on the website, according to ValueWalk. This gives users access to a half trillion tweets, and that number continues to rise.

Yi Zhuang, a search infrastructure engineer at Twitter, wrote in a blog post that you will be able to look for an entire conversation about any topic, such as sports, conferences and trending hashtags.

"Our long-standing goal has been to let people search through every Tweet ever published," Zhuang added.

The update is part of Twitter's goal of improving its "Tweet Index," which Zhuang says includes making it cost effective and easier for people to use, PC Magazine reported. Steps the company has taken to grow the index include creating a small "historical" index of about 2 billion top tweets in 2012, as well as growing the index to almost 20 billion tweets and improving its storage platform in 2013.

"In 2014, we built the full index with a multi-tier architecture, focusing on scalability and operability," Zhuang said.

Twitter users worried about people seeing embarrassing tweets they've made in their early days on the site have several options, which include deleting their accounts entirely, which can be seen as either effective or extreme, The Guardian reported. Users can also delete tweets manually or delete tweets after a week, month, year or specific date with the Tweet Delete app.

While Twitter showed more current tweets with the highest engagement before the update, the site now shows all results considered relevant, ABC News reported.

All users have to do now is enter a person's username and a keyword, and they will be able to see all kinds of tweets from the past they've never seen before.
