• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ((ky sang) OR (ky tang)) tao hai. ((hieu ve) or (hieu va)) cam xuc va hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ((ky sang) OR (ky tang)) tao hai. ((hieu ve) OR (hieu va)) cam xuc va hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ((ky sang) OR (ky tang)) tao hai. ((hieu ve) or (hieu va)) cam xuc va hanh vi cua te*".
