Thanks for the reply!
Sorry I should have been a bit more specific -- I removed "ORDER BY tags". One will of course get the same answer abcde every time when ordering by tags. This only shows that the nodes are reachable, which is true, but the actual path returned is not a DFS. While it is understandable that two searches may produce different results (child choice ordering etc), regardless the paths are not DFS.
As to versions, I have actually tried a number of them, but specifically/most pointedly the sandbox data science version. looking under the hood, it's still v3 which is perhaps telling?
Neo4j Browser version: 3.2.20
Neo4j Server version: 3.5.11 (enterprise)
Not sure which version of the plugin the sandbox is running. I just figured sandbox demo would be the most representative/most likely to work.
That being said, I've tried locally on 4.0.4 Enterprise with GDS 1.2.1 with the same results.
