• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky sang) OR (ky tang)) lap hoi. hieu ve cam ((duc va) OR (luc va)) hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky sang) OR (ky tang)) lap hoi. hieu ve cam ((duc va) or (luc va)) hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky sang) OR (ky tang)) lap hoi. hieu ve cam ((duc va) or (luc va)) hanh vi cua te*.
