• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - anh huong cua han ((trong dan) OR (trong tan)) ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - anh huong cua han ((trong dan) OR (trong tan)) ((toan cau) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - anh huong cua han ((trong dan) OR (trong tan)) ((toan cau) or (toan tap))*.
