• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - thanh ((tien viet) OR (trien viet)) hung trong dang toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) xanh - thanh ((tien viet) OR (trien viet)) hung trong dang toan ban*".
