• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (trieu tinh)) - hanh trang hua khong cong anh ((tuan cao) OR (toan cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (trieu tinh)) - hanh trang hua khong cong anh ((tuan cao) OR (toan cao))".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (trieu tinh)) - hanh trang hua khong cong anh ((tuan cao) OR (toan cao))*.
