Thank you Luca. This is just a suggestion from a newcomer to OrientDB, but I followed the Udemy Course and read what docs I could and I think one of my main confusion points was the difference between how edges vs relationships/links worked, especially with regard to query. Because OrientDB supports both Graph and Document model, it might be useful to point out early in the docs what the expand() function is used for. I think I was coming at it from the misconception that everything worked for graph queries, and lead myself to some frustration. Two other more specific points that lead me down the wrong path:
1) The Udemy course still shows the "traverse" operator in the section on graph traversal. 2) This page: http://orientdb.com/docs/last/orientdb.wiki/SQL-Traverse.html#using-traverse-with-graph-model-and-api refers to the V.out, E.in style of query which was not working. Thanks for all your help! I really appreciate it.
