• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - anh thong quang trung huong ((dan toan) OR (((van toan) OR (van tuan)))) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - anh thong quang trung huong ((dan toan) or (((van toan) OR (van tuan)))) cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - anh thong quang trung huong ((dan toan) or (((van toan) OR (van tuan)))) cao*.
