• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - canh ((tranh va) OR (tranh van)) thong duong dan phan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - canh ((tranh va) or (tranh van)) thong duong dan phan cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - canh ((tranh va) or (tranh van)) thong duong dan phan cau*.
