Google has begun rolling out a beta version of Social Search, which enables users to make Google searches more personal by including content from friends and online contacts.
The facility is being rolled out in English, but is still in beta, which means Google believes there is still some work to done on improving the service.
"We think there is tremendous potential for social information to improve search, and we are just beginning to scratch the surface," said Social Search team members in a blog post.
The concept is simple. For every Google search, users will see a list of relevant content, such as blog posts, drawn from their friends and contacts under the heading "Results from your social circle".
Anyone searching for images will see relevant pictures from people in their social circle in the search results that have been published on photo-sharing sites such as Picasa Web Albums and Flickr.
Social Search on Google requires a Google Account and a Google Profile that includes contact information and links to other social internet services such as Twitter.
