• If you are trying to use Boolean operators, they must be ALL CAPS: o ((cua tinh) OR (va tinh)) - hanh tranh cua nhung cong dan ((chan cap) OR (cao cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "o ((cua tinh) or (va tinh)) - hanh tranh cua nhung cong dan ((chan cap) OR (cao cap))~".
• Adding a wildcard symbol may retrieve word variants: o ((cua tinh) or (va tinh)) - hanh tranh cua nhung cong dan ((chan cap) OR (cao cap))*.
