Hi Steve,
Try this
SELECT expand(person) FROM (
MATCH {class: Person, as: person, where: (givenname =
'William')}.in(){while: ($depth = 0 OR givenname != 'George'), where:
(givenname = 'George')} RETURN person
)
The $depth = 0 guarantees that you don't stop traversing immediately;
the givenname
!= 'George' just stops traversing as soon as you find a "George", I guess
it is what you want (you don't need duplicates)
Thanks
Luigi
