• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis c sea transport plan marc ) or ( luis 3 debt transfer ((bot a) OR (both a)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis c sea transport plan marc ) or ( luis 3 debt transfer ((bot a) OR (both a)) ))*.
