• If you are trying to use Boolean operators, they must be ALL CAPS: chao ((chua nang) OR (chuc nang)) - hanh tranh cua cong song lanh ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao ((chua nang) OR (chuc nang)) - hanh tranh cua cong song lanh ((toan cau) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: chao ((chua nang) OR (chuc nang)) - hanh tranh cua cong song lanh ((toan cau) or (toan tap))*.
