• If you are trying to use Boolean operators, they must be ALL CAPS: (( luis ((e risk) OR (2 risk)) transfer fee cao ) OR ( luis f slovakia's transport fuel macao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis ((e risk) OR (2 risk)) transfer fee cao ) or ( luis f slovakia's transport fuel macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis ((e risk) OR (2 risk)) transfer fee cao ) or ( luis f slovakia's transport fuel macao ))*.
