• If you are trying to use Boolean operators, they must be ALL CAPS: ho chiet tach - ((canh ban) OR (can ban)) cua thuong cong ((dan chan) OR (dan gian)) dau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - ((canh ban) OR (can ban)) cua thuong cong ((dan chan) or (dan gian)) dau*".
