• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((canh tranh) OR (thanh trung)) ((va dong) OR (xa dong)) huong thanh san tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((canh tranh) or (thanh trung)) ((va dong) OR (xa dong)) huong thanh san tap*".
