• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (so sach)) ky tang ma hoi. lieu ((va cham) OR (va tham)) soc manh thanh lap chau tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (so sach)) ky tang ma hoi. lieu ((va cham) OR (va tham)) soc manh thanh lap chau tre*.
