If the number of properties is greater than n, return a subgraph in Neo4j

Question

This question is a direct extension of a question I asked previously.

Say I have a graph database that looks like this:

Just like the previous question

Answer 1

This query will filter out all sub-paths from the results:

MATCH p=(a:person)-[:RELATED_TO*]->(b:person)
WHERE
  NOT ()-[:RELATED_TO]->(a) AND
  NOT (b)-[:RELATED_TO]->() AND
  2 < REDUCE(s = 0, x IN NODES(p) | CASE WHEN x. SomeProperty = 'Yes' THEN s + 1 ELSE s END)
RETURN p;

Explanation:

• NOT ()-[:RELATED_TO]->(a) is true if the a node is not the at the end of a RELATED_TO relationship.
• NOT (b)-[:RELATED_TO]->() is true if the b node is not at the start of a RELATED_TO relationship.

Therefore, a matching path cannot be a sub-path.
