• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien manh - thanh trung ((((tuan nhung) OR (quan nhung))) OR (cua nhung)) hong manh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien manh - thanh trung ((((tuan nhung) OR (quan nhung))) or (cua nhung)) hong manh toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc hien manh - thanh trung ((((tuan nhung) OR (quan nhung))) or (cua nhung)) hong manh toan cao*.
