• If you are trying to use Boolean operators, they must be ALL CAPS: (( the urban ((smart series) OR (smart serious)) ) OR ( the urban hino series )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( the urban ((smart series) OR (smart serious)) ) or ( the urban hino series ))".
• Adding a wildcard symbol may retrieve word variants: (( the urban ((smart series) OR (smart serious)) ) or ( the urban hino series ))*.
