Hi @Batista,
I'm not sure if I completely understand now what you're trying to do here. But, I think what you have are several indicator columns now and you would like a single column that shows if any one of them was present. In those situations, I create a Formula Column taking the Max() of the indicator columns. You can do this with New Formula Column right in the data table by selecting the columns, then Right Click a column header > New Formula Column > Combine > Maximum. You will then have a single indicator of the presence of any of those terms.
If this isn't what you're after, could you explain a little bit more about your goal here? It would also be helpful if you could provide a piece of your data, or at least a screenshot so we can better see how your data are currently organized.
