• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach thue)) nang ((ma hoi) OR (ma hoa)). hieu qua cam xuc va hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) or (sach thue)) nang ((ma hoi) OR (ma hoa)). hieu qua cam xuc va hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ty) or (sach thue)) nang ((ma hoi) OR (ma hoa)). hieu qua cam xuc va hanh vi cua te*.
