ignorereflex

The @ignorereflex directive forces the removal of child nodes that are reachable from themselves as a parent, through any path in the query result

Query Example: all the co-actors of Rutger Hauer. Without @ignorereflex, the result would also include Rutger Hauer for every movie.

{
  coactors(func: eq(name@en, "Rutger Hauer")) @ignorereflex {
    actor.film {
      performance.film {
        starring {
          performance.actor {
            name@en
          }
        }
      }
    }
  }
}
