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