• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis c cash transfers ai mark ) or ( luis 2.1 land transfers ((ideas 4) OR (idea 4)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis c cash transfers ai mark ) or ( luis 2.1 land transfers ((ideas 4) OR (idea 4)) ))*.
