• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh ((tung cua) OR (tuong cua)) khong cong ((tan toan) OR (van toan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh ((tung cua) or (tuong cua)) khong cong ((tan toan) OR (van toan)) cao".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh ((tung cua) or (tuong cua)) khong cong ((tan toan) OR (van toan)) cao*.
