• If you are trying to use Boolean operators, they must be ALL CAPS: thuyet ((thiet nang) OR (thi nang)) - canh tranh qua trong cong manh ((toan cau) OR (toan ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuyet ((thiet nang) OR (thi nang)) - canh tranh qua trong cong manh ((toan cau) or (toan ban))".
