• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu sach) OR (hieu cach)) - hanh tang cua truong phuong danh ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu sach) or (hieu cach)) - hanh tang cua truong phuong danh ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu sach) or (hieu cach)) - hanh tang cua truong phuong danh ((toan cau) OR (toan ban))*.
