• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty tang van hoi. hieu ((qua cai) or (qua ca)) duc va hanh de ((su triet) OR (su tien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty tang van hoi. hieu ((qua cai) OR (qua ca)) duc va hanh de ((su triet) OR (su tien)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty tang van hoi. hieu ((qua cai) or (qua ca)) duc va hanh de ((su triet) OR (su tien))".
• Adding a wildcard symbol may retrieve word variants: thu sach ty tang van hoi. hieu ((qua cai) or (qua ca)) duc va hanh de ((su triet) OR (su tien))*.
