• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu tinh)) - hanh trang cua thong cong dan ((than cap) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) OR (chieu tinh)) - hanh trang cua thong cong dan ((than cap) or (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) OR (chieu tinh)) - hanh trang cua thong cong dan ((than cap) or (toan cau))*.
