• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) OR (tu san)) ky dang ((luat hoi) or (lai hoi)). hieu ve cam xuc va hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu san)) ky dang ((luat hoi) OR (lai hoi)). hieu ve cam xuc va hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu san)) ky dang ((luat hoi) or (lai hoi)). hieu ve cam xuc va hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) OR (tu san)) ky dang ((luat hoi) or (lai hoi)). hieu ve cam xuc va hanh vi cua te*.
