I have few posts that I related but not by their content, but by their logic, e.g.:
"apples", "pears", "plums" - there is no content relation, except all are fruits. YARPP is dumb and does not see this.
So, I added this text at the end of these posts:
"Memories from the Land of Long White Cloud"
YARPP still does not see relation! So, how to force YARPP to see the relation?
