• Performing a fuzzy search may retrieve terms with similar spellings: ((tu van) OR (tu va)) ky lang xa hoi. thien van coc ((luc va) or (tuc va)) thanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu van) OR (tu va)) ky lang xa hoi. thien van coc ((luc va) OR (tuc va)) thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu van) OR (tu va)) ky lang xa hoi. thien van coc ((luc va) or (tuc va)) thanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((tu van) OR (tu va)) ky lang xa hoi. thien van coc ((luc va) or (tuc va)) thanh vi cua te*.
