• Performing a fuzzy search may retrieve terms with similar spellings: tu ((cai ky) OR (cao ky)) lang van hoi. hieu ve cham soc ban thanh san ((cau treo) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((cai ky) OR (cao ky)) lang van hoi. hieu ve cham soc ban thanh san ((cau treo) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((cai ky) OR (cao ky)) lang van hoi. hieu ve cham soc ban thanh san ((cau treo) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: tu ((cai ky) OR (cao ky)) lang van hoi. hieu ve cham soc ban thanh san ((cau treo) or (su triet))*.
