Last month, Twitter released an update to their search function that allowed users to search for any tweet that had ever been posted, from Twitter’s launch to tweets being posted right now. Twitter’s search had worked similarly to this beforehand, though it didn’t quite extend all the way back to the beginning of Twitter. Not wanting to be left behind, Facebook has updated their own search function in response and finally is now allowing users to find older posts.
Facebook has been working on this feature for more than a year. Searching is customized for each user, so that users can search only through posts that have been shared with them, rather than all posts on Facebook. Users simply have to type in any word and can find all posts that use that word or phrase. These can be specified to certain users, so that you could type in a friend’s name and find any posts that they might have written that used the word “Florida” or “restaurant.”
There are plenty of applications for this new feature that could benefit Facebook and even build it up as a competitor to Yelp or Google. For instance, now any user can type in “happy hour” or “great burger” and find every time that one of their friends referenced this sort of thing. It allows Facebook to operate as a service for friend-based recommendations. The search function can also be used to find friends’ opinions regarding major news events by typing in keywords like “ebola” or “Ferguson.” With Facebook making everyone’s posts that much more public, your privacy settings may be more important than ever, so it may be worth taking a look at those again now that Facebook has rolled this feature out.
