• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky lang xa hoi. hieu van cham xuc ((va han) or (va hanh)) tri ((va thieu) OR (va tieu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky lang xa hoi. hieu van cham xuc ((va han) OR (va hanh)) tri ((va thieu) OR (va tieu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky lang xa hoi. hieu van cham xuc ((va han) or (va hanh)) tri ((va thieu) OR (va tieu))".
• Adding a wildcard symbol may retrieve word variants: tu sach ky lang xa hoi. hieu van cham xuc ((va han) or (va hanh)) tri ((va thieu) OR (va tieu))*.
