Regardless of using the reference row filter or the set operator to find terms common to training and test documents, there's a particular term that is found in training but not testing. What could be the reason? As of now I have to remove this term from training to build classification models. Is it a case of duplicate rows in training ? ---

What term is it? Can you provide data or a workflow? When comparing terms, the tags are also taken into account. Cheers, Kilian ---
