Description

This fails in OLAP.

g.V().match(
  as('a').out('sungBy').as('b'),
  as('a').out('writtenBy').as('b')).
select('a','b').by('name')

However, this passes:

g.V().match(
  as('a').out('sungBy').as('b'),
  as('a').out('writtenBy').as('b'),
  as('a').values('name').as('c'),
  as('b').values('name').as('d')).
select('c','d')

Can all "local star graph" OLAP problems be strategized into MatchSteps? It would be a decoration strategy of some sort.... dkuppitz
