I was surprised to see no negative logic in basic filter operations like 'Contains':
I thought I had commented further but I guess not. In general, I think dataiku should offer visual recipe filter options akin to workbook software, with negative logic for every type of filter. Here is what I allow in a Python based SQL query engine I wrote; perhaps it can give some food for thought.
