I am using the join operator to find similar entires in two data sets. However, my output is coming up empty. I know there are similar entries in the data, but they aren't showing up. 

 

Thoughts on what I am doing wrong??

    Dear motley,

     

    a join is not searching for similar things put joining ("appending horizontally") those examples who have the exact same ID.

    Hello @amotley, 

     

    If you think having the join/intersect and other data blending operators rely on more than ID, then please submit your idea here and we can vote it
