Hi - I'm stuck with question 2 in part 3 of the Data Science training. https://neo4j.com/graphacademy/online-training/data-science/part-3/ After trying to work out the answer in the normal way I gave up and resorted to a brute force approach. I have...
How? Clicking the "Open" button doesn't appear to do anything if an existing Neo4j Browser window is already open.
I've now gone through exercise 8 up to 8.12 twice. The first time I would read an exercise then type out how I thought the answer should be formed, go to the next page (where the solution displays) and check to ensure what I wrote matched before play...

Hi there, I'm studying the query below, and wondering why the result co-actors didn't show actor Meg Ryan herself? Suppose after we get all movie list in variable m, then the second MATCH pattern should list out all the actors who ACTED_IN movies lis...
On this page - https://neo4j.com/graphacademy/online-training/introduction-to-neo4j/part-6/ "If were were to attempt to delete the Liam Neeson node without first deleting its relationships:"
So I would like to ask the simplest question out there. But where better to ask. In the graph academy: Neo4j-administration, managing a neo4j database I am asked to enter "bin/neo4j-admin set-initial-password newPassword" to change password. I have b...
I went through the online training, except having trouble on only one question in Admin online training (Security 5.2). I thought the answer should be all of the answers . However, it did not went through. My understanding is that it requires SSL p...
