• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (thien anh)) - lanh manh cua khong cong tan ((toan ban) OR (van ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) OR (thien anh)) - lanh manh cua khong cong tan ((toan ban) or (van ban))".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) OR (thien anh)) - lanh manh cua khong cong tan ((toan ban) or (van ban))*.
