Facebook is testing an in-app keyword search engine on a small number of iOS users in the US, enabling them to find and share links to articles without leaving the app. Currently, users have to already have left the app environment and jump into a browser to search for the content they want to share, and copy the link, and then go back into the Facebook app. This new update offers a much more streamlined user journey, allowing them to remain within the Facebook ecosystem and never have to leave the app.
