my original data:

I only use x1 to do some testing on the code to see if it could work. Now i can get the correct matching for x1. But i get the wrong output for 'non matching' . my expected output of 'non matching' for x1 is Adidas              22222 11111only because 'x1=> 99999' are presented in both new data and old data. And i am not sure how to continue with the 'y1, x2, and y2' ...
