• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (theo chieu)) sach - thanh tung va ((nang nong) OR (nang song)) dan than ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (theo chieu)) sach - thanh tung va ((nang nong) OR (nang song)) dan than ban".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (theo chieu)) sach - thanh tung va ((nang nong) OR (nang song)) dan than ban*.
