• If you are trying to use Boolean operators, they must be ALL CAPS: doc chieu sach - anh quang tran quang luong tap ((toan cau) OR (((toan cao) OR (toan ban))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc chieu sach - anh quang tran quang luong tap ((toan cau) or (((toan cao) OR (toan ban))))~".
• Adding a wildcard symbol may retrieve word variants: doc chieu sach - anh quang tran quang luong tap ((toan cau) or (((toan cao) OR (toan ban))))*.
