• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((trien tinh) OR (thien minh)) - hanh trang hua chong cong ((tan than) OR (ban than)) cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((trien tinh) or (thien minh)) - hanh trang hua chong cong ((tan than) OR (ban than)) cao*".
