• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((chuc danh) OR (chu manh)) - hanh tranh cua bang cong tan ((chan cau) OR (chinh cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chuc danh) or (chu manh)) - hanh tranh cua bang cong tan ((chan cau) OR (chinh cau))~".
• Adding a wildcard symbol may retrieve word variants: cho ((chuc danh) or (chu manh)) - hanh tranh cua bang cong tan ((chan cau) OR (chinh cau))*.
