• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((lanh tranh) OR (hanh trang)) va han tong dan ((toan tap) OR (toan ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((lanh tranh) or (hanh trang)) va han tong dan ((toan tap) OR (toan ban))*".
