• If you are trying to use Boolean operators, they must be ALL CAPS: (("tu mach co hoc") OR ((((("te choa moi hoa") OR ("te ho moi hoa"))) OR ("te sach ba hoa"))))~.
• Removing quotes may allow a broader search: (( tu mach co hoc ) or ((((( te choa moi hoa ) or ( te ho moi hoa ))) or ( te sach ba hoa ))))~.
• Adding a wildcard symbol may retrieve word variants: (("tu mach co hoc") or ((((("te choa moi hoa") or ("te ho moi hoa"))) or ("te sach ba hoa"))))*.
