• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tay) OR (xach tay)) cong hoa hoi. hieu ke che thuoc ((van anh) OR (van minh)) doi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tay) or (xach tay)) cong hoa hoi. hieu ke che thuoc ((van anh) OR (van minh)) doi cua te~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach tay) or (xach tay)) cong hoa hoi. hieu ke che thuoc ((van anh) OR (van minh)) doi cua te*.
