• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sach) OR (chieu sang)) - thanh trung tuan phong tuong dan ((phan dau) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) OR (chieu sang)) - thanh trung tuan phong tuong dan ((phan dau) or (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sach) OR (chieu sang)) - thanh trung tuan phong tuong dan ((phan dau) or (khan cap))*.
