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