• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) OR (tu sach)) ky nang ((x hoi) or (co hai)). hieu ve cam xuc tan hanh tai cuc du~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky nang ((x hoi) OR (co hai)). hieu ve cam xuc tan hanh tai cuc du.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky nang ((x hoi) or (co hai)). hieu ve cam xuc tan hanh tai cuc du".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) OR (tu sach)) ky nang ((x hoi) or (co hai)). hieu ve cam xuc tan hanh tai cuc du*.
