• If you are trying to use Boolean operators, they must be ALL CAPS: (( luis 2 set transport bei mary ) OR ( louis 3.1 heat transfer ((cash aid) OR (cash a)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis 2 set transport bei mary ) or ( louis 3.1 heat transfer ((cash aid) OR (cash a)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis 2 set transport bei mary ) or ( louis 3.1 heat transfer ((cash aid) OR (cash a)) ))*.
