• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sang - hanh tan van nang cong tac ((((phan cau) OR (phan cac))) or (khan cap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - hanh tan van nang cong tac ((((phan cau) OR (phan cac))) OR (khan cap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - hanh tan van nang cong tac ((((phan cau) OR (phan cac))) or (khan cap))*".
