Thank you so much, I'll try that and I'll let you know :)
I have one more question, what is the difference between these two queries?
Is the first one faster?
Match (u:User {userid=1})-[f:Friends{status=2}]-(uu:User) RETURN COUNT (uu)
Match (u:User) -[f:Friends]- (uu:User) WHERE u.userid=1 AND f.status =2
RETURN COUNT (uu);
Best,
Reihane
