• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty nang ((((mai hoi) OR (mai khoi))) or (lai hoi)). hieu ve cam xuc va thanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty nang ((((mai hoi) OR (mai khoi))) OR (lai hoi)). hieu ve cam xuc va thanh hai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang ((((mai hoi) OR (mai khoi))) or (lai hoi)). hieu ve cam xuc va thanh hai cua tre*".
