• Performing a fuzzy search may retrieve terms with similar spellings: tu van ky nang ma hoi. hieu vien chat luc va ((((danh co) OR (danh ca))) or (doanh co)) cua su~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu van ky nang ma hoi. hieu vien chat luc va ((((danh co) OR (danh ca))) OR (doanh co)) cua su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu van ky nang ma hoi. hieu vien chat luc va ((((danh co) OR (danh ca))) or (doanh co)) cua su".
• Adding a wildcard symbol may retrieve word variants: tu van ky nang ma hoi. hieu vien chat luc va ((((danh co) OR (danh ca))) or (doanh co)) cua su*.
