Do you know that Facebook saves all your search history? Shocked? You can see everything you have searched so far on Facebook. To view your search history on Facebook, go to your Facebook profile page and click on Activity Log link at top.
On the Activity Log page, click on the drop down list of items in the top right corner that says, ‘Apps and Posts’. Select ‘search’ from this list of items.
This will display all your searches on Facebook in the chronological order. Here you can see everything you have ever written in the Facebook search bar from the time you have created your Facebook account to the present day.
Deleting Your Search History on Facebook
To delete all your search history from Facebook, click on ‘Clear Searches’ button at the top. You can also selectively delete items individually by clicking on the small cross sign that appear when you hover over any Facebook search history item.
Since your Facebook search history is only visible to you, its not much of a Facebook privacy issue. Facebook probably saves the history only to show relevant advertisements in sidebar. So, if you want it to display relevant ads, then don’t delete your Facebook history.
