Facebook users urged to check privacy settings

The site has introduced an update to its search feature which includes every public post ever made

Facebook users are being encouraged to double-check their privacy settings after the social network introduced an update to its search feature which adds almost 2 trillion older posts by its members to the index.

Previously, Facebook's search feature was largely limited to groups, events and locations, with individuals' public posts difficult to find without directly navigating to the user's profile page.
