I have, let's say a graph with 50 nodes. With Cypher I find 3 possible paths from node A to node B (the result of the Cypher query is also a graph .. a sub-graph) MATCH p=((a:label {Pro1:'A'})-[*7]->(b:label {Pro1:'B'})) RETURN p On the path from A t...

I use cypher like this: "MATCH p=allShortestPaths((h)-[*1..20]->(k {value:true}))" to search all pair shortest path, can I add path weight into this cypher? Instead of call gds algo?
Hi, I just run to make the relationship between two nodes in python. Run the raw cypher query with tx. When I run the query in neo4j Desktop It works, But doesn't work in python code. Well, it looks like work, but the database doesn't update. Any com...
