Starting tomorrow, Facebook will start rolling out Graph Search to users who have their language set to 'US English'.
The new feature allows users to conduct more personalised and advanced searches, for example like 'Australian musicians my friends like' or 'photos of my girlfriend in 2009', which will then bring up specialized results.
Facebook plans to notify users to check "who can see my stuff" under their privacy settings.
"The goal is to avoid bad surprises," Nicky Jackson Colaco, privacy and safety manager at Facebook, told AAP.
According to US TV channel ABC News several hundreds of millions of people will get it this week.
Facebook first unveiled the social search tool in January, but up until now the feature has only been in beta for a few select users.
Back in January Facebook CEO Mark Zuckerberg described the product as different to search sites like Google, labelling it "precise."
“Web search is designed to take any open-ended query and give you links that might have answers. Graph Search is designed to take a precise query and give you an answer, rather than links that might provide an answer,” he said.
Meanwhile Facebook's new-look Timeline is still also in beta, with no news on a broader rollout.
