• Performing a fuzzy search may retrieve terms with similar spellings: vu lanh dao ((lang xa) or (nang ma)) hoi. hieu ve cam luc va danh ((vi cua) OR (di cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu lanh dao ((lang xa) OR (nang ma)) hoi. hieu ve cam luc va danh ((vi cua) OR (di cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu lanh dao ((lang xa) or (nang ma)) hoi. hieu ve cam luc va danh ((vi cua) OR (di cua)) triet".
• Adding a wildcard symbol may retrieve word variants: vu lanh dao ((lang xa) or (nang ma)) hoi. hieu ve cam luc va danh ((vi cua) OR (di cua)) triet*.
