• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh trung ((ha nhung) OR (hay nhung)) ((cong dan) OR (cong san)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh trung ((ha nhung) OR (hay nhung)) ((cong dan) or (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh trung ((ha nhung) OR (hay nhung)) ((cong dan) or (cong san)) toan cao*.
