• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((trien dich) OR (hieu lang)) - hanh trinh cua dang cong tan ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((trien dich) or (hieu lang)) - hanh trinh cua dang cong tan ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ho ((trien dich) or (hieu lang)) - hanh trinh cua dang cong tan ((toan cao) OR (toan ban))*.
