• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang ((x hoi) OR (x ho)). hieu ve cam xuc van ((thanh ban) OR (thanh bac)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang ((x hoi) or (x ho)). hieu ve cam xuc van ((thanh ban) OR (thanh bac)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang ((x hoi) or (x ho)). hieu ve cam xuc van ((thanh ban) OR (thanh bac)) cua tre*.
