[MarkLogic Dev General] Forests and Collections querying problem

[Danny Sokolsky]

Does this query also return nothing:

doc("mde:mdc://5ca78568-3bd5-46f9-bfef-1aa36f3eb3f8")/Metacard

If so, maybe there is nothing in that document under Metacard?

Also try this:

doc("mde:mdc://5ca78568-3bd5-46f9-bfef-1aa36f3eb3f8")/*
