I have a doubt in query 9 of this article here
In query 7 the author has calculated the cosine similarity and made a new realtionship called similarity.
But in query 9 it has been used to find all the customers who have some similarity relationship with another customer :
But all customers will have some similarity. If we wanted to use the cosine similarity we have calculated we should have searched the customers who have the highest similarity points with me:Customer.
Can you please explain if i am right or wrong here?
