Use the drop down box to choose the type of resources you want to see. You can hold down the Ctrl key while clicking to display more than one resource type. If you want the results to be resources that are either type A or B, select 'Is One Of'. If you want the results to be resources that are A and B, select 'Is All Of'. If you want to find all resources that are not of type A or type B select 'Is None Of'. Clear as mud? Excellent.
