I have created an embedded Neo4J in a Java project like this:
graphDb = new GraphDatabaseFactory()
.newEmbeddedDatabaseBuilder("db")
.setConfig(GraphDatabaseSettings.node_keys_indexable, "movieId, userId, rating, genre")
.setConfig(GraphDatabaseSettings.node_auto_indexing, "true")
.newGraphDatabase();
I have verified that the index is created, and it has the name that I expect:
Index<Node> index = graphDb.index().forNodes("movieId");
System.out.println("::: Verify Index Name :::");
System.out.println(index.getName());
The console shows:
::: Verify Index Name :::
movieId
I can find the node using the Java API
ReadableIndex<Node> graphDbIndex = graphDb.index().getNodeAutoIndexer().getAutoIndex();
Node movie = graphDbIndex.get("movieId", 2).getSingle();
System.out.println("::: Get with Java API Result :::");
System.out.println("MovieId: " + movie.getProperty("movieId"));
System.out.println("Title: " + movie.getProperty("title"))
The console shows
::: Get with Java API Result :::
MovieId: 2
Title: Jumanji (1995)
But when I try with Cypher this is the result
ExecutionEngine engine = new ExecutionEngine(graphDb);
ExecutionResult result = engine.execute("start movie=node:movieId(movieId='2') return movie, movie.title");
System.out.println("::: get with Cypher Result :::");
System.out.println(result);
The console shows
::: get with Cypher Result :::
+---------------------+
| movie | movie.title |
+---------------------+
+---------------------+

Am I doing something very wrong or have I just missed something obvious?
Thanks.
node_auto_index
the indexed property names"movieId, userId, rating, genre"
