• Performing a fuzzy search may retrieve terms with similar spellings: su sac ((ky tang) or (ky dang)) ((mai hoi) OR (mai khoi)). hieu ve cam xuc va thanh va hoa viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky tang) OR (ky dang)) ((mai hoi) OR (mai khoi)). hieu ve cam xuc va thanh va hoa viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky tang) or (ky dang)) ((mai hoi) OR (mai khoi)). hieu ve cam xuc va thanh va hoa viet".
• Adding a wildcard symbol may retrieve word variants: su sac ((ky tang) or (ky dang)) ((mai hoi) OR (mai khoi)). hieu ve cam xuc va thanh va hoa viet*.
