|you can use three boolean parameter: 'AND', 'OR' & 'NOT'|
your results are depending on this Boolean operation!
e.g. [Film] AND [Country] -> you get the records, where film and country are identical with your selection
e.g. [Film] OR [Country] -> your result is the ammount, where film or country is identical with your selection
e.g. AND NOT [film] -> you will get all films, but not the selected
