• If you are trying to use Boolean operators, they must be ALL CAPS: ((thi chieu) OR (ho chieu)) xanh - thanh ((trung va) OR (truong va)) thong cong dan than cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi chieu) or (ho chieu)) xanh - thanh ((trung va) OR (truong va)) thong cong dan than cao*".
