If you're only returning nodes on depth=X (let's say X=4) and want to filter
relationships all along the way then maybe I'd use something along the lines
of:
"prune evaluator": { "language": "javascript", "body":
"position.lastRelationship().getProperty(\"userGroupId\",0) == 111;" }
"return filter": { "language": "javascript", "body":
"position.length() == 4 &&
position.lastRelationship().getProperty(\"userGroupId\",0) == 111;" }
So that branches only branches that have "userGroupId"==111 will continue to
be traversed and only paths of length 4 will be returned where the last
relationship has "userGroupId"==111 will be returned. (untested code).
