Given the interesting conversation about EXISTS, I have a slightly related question


  select *
{ graph <eg:graph> {
       ?s <eg:b> ?o
       FILTER EXISTS {
           ?s <eg:c> ?o
      }
  }
}


is the <eg:c> matched against the default graph or <eg:graph>?

I sometimes get results for this sort of query that surprise me, and so I tend to explicitly repeat the graph scope.
