• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((luis 3) OR (luis c)) social transformations a car ) or ( luis 2 central transfer und macht ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((luis 3) OR (luis c)) social transformations a car ) or ( luis 2 central transfer und macht ))*.
