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