• If you are trying to use Boolean operators, they must be ALL CAPS: hoi ((chu tinh) OR (chau tinh)) - hanh mang luan dung cong dan ((toan cau) OR (toan ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoi ((chu tinh) OR (chau tinh)) - hanh mang luan dung cong dan ((toan cau) or (toan ban))".
• Adding a wildcard symbol may retrieve word variants: hoi ((chu tinh) OR (chau tinh)) - hanh mang luan dung cong dan ((toan cau) or (toan ban))*.
