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