• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) tinh - canh ((tranh van) OR (trinh van)) dung trong manh toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) tinh - canh ((tranh van) or (trinh van)) dung trong manh toan tap*".
