• If you are trying to use Boolean operators, they must be ALL CAPS: (( vagues ((one human) OR (one man)) transport fuel a ) OR ( guide a cas transfer a do ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( vagues ((one human) OR (one man)) transport fuel a ) or ( guide a cas transfer a do ))~".
• Adding a wildcard symbol may retrieve word variants: (( vagues ((one human) OR (one man)) transport fuel a ) or ( guide a cas transfer a do ))*.
