I just don't see how a Facebook search engine would work.
People go to Facebook to engage with their friends etc.
They just need to find ways to put more ads on the site. Eg stop the ad blockers. Or somehow start charging for some services.
And somehow drop the bid prices.
Facebook is now ahead of Google in world-wide Alexa traffic. No 1.
