• Performing a fuzzy search may retrieve terms with similar spellings: nuoc gac ky ((nang ma) or (nang cao)) hoi. hieu ve huu phuc van hang vi ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc gac ky ((nang ma) OR (nang cao)) hoi. hieu ve huu phuc van hang vi ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc gac ky ((nang ma) or (nang cao)) hoi. hieu ve huu phuc van hang vi ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: nuoc gac ky ((nang ma) or (nang cao)) hoi. hieu ve huu phuc van hang vi ((cua tre) OR (cua triet))*.
