Hello Philippe, i don't know the maximum number of values that a user may enter. But, if we can make it work or we can solve it just by limiting to 15/20 distinct values, I'm open to any suggestion.

Thanks Gianni for your answer. Unfortunately, the clients is used to old biapps analytics where there was an option called 'contains any' that can interpret the query as i asked in the question. And so, here it comes the requirement to reproduce something like that in OAC DV. Thanks, Mattia
