• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky ((nang xa) OR (nang x)) hoi. hieu ve cham xuc va hang tai ((va thieu) OR (va tieu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky ((nang xa) or (nang x)) hoi. hieu ve cham xuc va hang tai ((va thieu) OR (va tieu))".
