Your public search listing includes your name, profile picture, gender and network — basic information that is always visible to everyone. It also includes your friend list and your likes, activities and interests (to limit the visibility of this information, change the settings in the "Connecting on Facebook" section of your Privacy Settings). If you post anything to an open forum on the site (for example: posts and comments on public pages and open groups, the "Questions and Answers from Users" section of the Help Center), this post may also appear in search engines.
