• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - thanh trung ((cua thuong) OR (cua truong)) cong thanh ((chan tu) OR (cho tu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - thanh trung ((cua thuong) OR (cua truong)) cong thanh ((chan tu) or (cho tu))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - thanh trung ((cua thuong) OR (cua truong)) cong thanh ((chan tu) or (cho tu))*.
