How can I list the users with the most similar entries with ArangoDB

I started new project today. I have users table, tags table and user_tags edge for graph results.

I attached to users some tags on graph. How can I list the users with the most similar entries with ArangoDB.

For example:

• user id: 112 has 3 tags (tags ids: 50, 51, 52, 53)
• user id: 113 has 5 tags (tags ids: 52, 53, 54, 55, 56)
• user id: 114 has 4 tags (tags ids: 51, 52, 53, 54)
• user id: 115 has 2 tags (tags ids: 48, 49)

When i searched user id 112 user. The results should be similar to this:

1. user id: 114 (3 matches, 51, 52, 53)
2. user id: 113 (2 matches, 52, 53)

Non-common data should not come within results user id: 115

If no one knows arangodb solution, I can use neo4j if there is a solution with neo4j.

Thanks.

In cypher, this is the query :

MATCH (u1:User {id:114})-[:HAS_TAG]->(tag:Tag),
      (u:User)-[:HAS_TAG]->(tag:Tag)
WITH u, collect(id(tag)) AS tags
RETURN u, tags, size(tags) AS score
ORDER BY score DESC
