Facebook improve search feature to include public Post.

Facebook has made its search feature more powerful with latest update. The social network has announced Search FYI, an expanded search function that will allow users to find out what the world is saying about a particular topic.
                                        First up, Facebook search will now offer you better personalized suggestions when you tap into the search box and start typing. It will highlight things that are happening right now so you can follow popular stories as they unfold. For example, if you type “water” into the search box, Facebook will auto-suggest popular search terms and phrases, such as “water on Mars.” Next up, when you search, you will now see the most recent, relevant public posts along with posts from your friends. These search results are organized to help you quickly know what the world is saying about a topic in the moment.
