• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty hang mai hoi. hieu ((va tham) OR (((van tham) OR (van chat)))) luc va tinh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty hang mai hoi. hieu ((va tham) or (((van tham) OR (van chat)))) luc va tinh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: su sach ty hang mai hoi. hieu ((va tham) or (((van tham) OR (van chat)))) luc va tinh vi cua tre*.
