?[edgetype, name](vertex-collection)

returns edge collection

Examples (null corresponds to DB root vertex):

?[E, “Customer”](null) returns {Customer}

child(?[A, “name”](child(?[E, “Customer”](null)))) returns {“Jane”}

Abbreviated syntax (a la XPath):

• A/b = ?[E, “b”](A)

• A/@b = ?[A, “b”](A)

• A/>b = ?[R, “b”](A)
