• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang mo) OR (nang meo)) hoi. hieu va cam cuc ((ban hanh) OR (ban hang)) doi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang mo) OR (nang meo)) hoi. hieu va cam cuc ((ban hanh) or (ban hang)) doi cua te".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((nang mo) OR (nang meo)) hoi. hieu va cam cuc ((ban hanh) or (ban hang)) doi cua te*.
