• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky ((((lang hoa) OR (nang hoa))) or (lang ha)) hoi. hieu he nam thuc va nang hai cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((((lang hoa) OR (nang hoa))) OR (lang ha)) hoi. hieu he nam thuc va nang hai cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((((lang hoa) OR (nang hoa))) or (lang ha)) hoi. hieu he nam thuc va nang hai cua viet".
• Adding a wildcard symbol may retrieve word variants: te sac ky ((((lang hoa) OR (nang hoa))) or (lang ha)) hoi. hieu he nam thuc va nang hai cua viet*.
