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