Corrupted my Photos index

On installing this and importing the Pictures library, I started with a basic duplicate comparison to test the app. It turned up only 14 duplicate photos out of a library of 10s of thousands. Moreover, when I returned to Photos, all the custom albums and even the Faces settings I had taken days to set up were gone. Unbelievable. To make matters worse only a fraction of the photos I had on disk were visible.
