• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis 1 heat ((transfer a) OR (transfer 3)) cash ) or ( luis a heat transport air cacao ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis 1 heat ((transfer a) OR (transfer 3)) cash ) or ( luis a heat transport air cacao ))*.
