Slow query times for has() function (on play.dgraph.io)

The reason I said it looked like the dgraph.type isn’t built for the Freebase data was because when looking at the schema for the Freebase dataset, there were various other dgraph.[name] predicates mentioned, but not dgraph.type - so I made the erroneous assumption that it wasn’t built. Thanks for the correction.

Are there any other internal predicates that won’t be listed either in the schema in general, or specifically in the Ratel schema interface?

Thanks.
