• Performing a fuzzy search may retrieve terms with similar spellings: nuoc giao ly ((nang xa) or (lang xa)) hoi. hieu ve cau thuc va hang vi ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc giao ly ((nang xa) OR (lang xa)) hoi. hieu ve cau thuc va hang vi ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc giao ly ((nang xa) or (lang xa)) hoi. hieu ve cau thuc va hang vi ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: nuoc giao ly ((nang xa) or (lang xa)) hoi. hieu ve cau thuc va hang vi ((cua tre) OR (cuu tre))*.
