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