now I have a new idea bsed on
https://github.com/arangodb/arangodb/issues/1567 and my AQL are list as
follows:
for v1,e1,p1 in INBOUND 'node/p1' edge FILTER v.LABEL == 'MetaPerson'
for v2,e2,p2 in OUTBOUND v1 edge FILTER v2.LABEL == 'entity'
for v3,e3,p3 in OUTBOUND v2 edge FILTER v3.LABEL LIKE "%Event%"
for v4,e4,p4 in OUTBOUND v3 edge FILTER v4.LABEL == 'entity'
return {p1,p2,p3,p4}
and it could return results as I expected. However, I want to know if there
is a much more efficient method?
thx
