• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - canh ((tranh ha) OR (trinh xa)) truong cong ((bang than) OR (bang thanh)) ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - canh ((tranh ha) or (trinh xa)) truong cong ((bang than) OR (bang thanh)) ban".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - canh ((tranh ha) or (trinh xa)) truong cong ((bang than) OR (bang thanh)) ban*.
