• If you are trying to use Boolean operators, they must be ALL CAPS: thep ((thiet tach) OR (thuat tach)) - hanh mang cua dang huong ((dan toan) OR (dan than)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thep ((thiet tach) OR (thuat tach)) - hanh mang cua dang huong ((dan toan) or (dan than)) cau*".
