• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu quang - hanh trinh cua trong cong dan ((((nhuan tai) OR (han tai))) or (thanh ban))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu quang - hanh trinh cua trong cong dan ((((nhuan tai) OR (han tai))) OR (thanh ban))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu quang - hanh trinh cua trong cong dan ((((nhuan tai) OR (han tai))) or (thanh ban))*".
