• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chinh sach)) - hanh tranh ((cua hung) OR (cua nhung)) vuong manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chinh sach)) - hanh tranh ((cua hung) or (cua nhung)) vuong manh toan cao".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chinh sach)) - hanh tranh ((cua hung) or (cua nhung)) vuong manh toan cao*.
