• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((chu sang) OR (chieu sang)) - hanh trung cua khong ((cong dan) OR (cong san)) phan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu sang) or (chieu sang)) - hanh trung cua khong ((cong dan) OR (cong san)) phan cau".
• Adding a wildcard symbol may retrieve word variants: cho ((chu sang) or (chieu sang)) - hanh trung cua khong ((cong dan) OR (cong san)) phan cau*.
