• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - canh ((doanh cua) OR (doanh luan)) nhung hoang van ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - canh ((doanh cua) OR (doanh luan)) nhung hoang van ((toan cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - canh ((doanh cua) OR (doanh luan)) nhung hoang van ((toan cau) or (toan ban))*.
