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