• Performing a fuzzy search may retrieve terms with similar spellings: ((tu dan) OR (cu dan)) ky nang van hoa. hieu van cam luc van hanh di ((va triet) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu dan) OR (cu dan)) ky nang van hoa. hieu van cam luc van hanh di ((va triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu dan) OR (cu dan)) ky nang van hoa. hieu van cam luc van hanh di ((va triet) or (cua viet))".
• Adding a wildcard symbol may retrieve word variants: ((tu dan) OR (cu dan)) ky nang van hoa. hieu van cam luc van hanh di ((va triet) or (cua viet))*.
