• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) lang - manh trung cua phuong dung ((va toan) OR (van toan)) tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) lang - manh trung cua phuong dung ((va toan) OR (van toan)) tap".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) lang - manh trung cua phuong dung ((va toan) OR (van toan)) tap*.
