• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sang) OR (tu san)) ky ((lang xa) or (lang ha)) hoi. hieu qua cam xuc van hang di hoa viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sang) OR (tu san)) ky ((lang xa) OR (lang ha)) hoi. hieu qua cam xuc van hang di hoa viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sang) OR (tu san)) ky ((lang xa) or (lang ha)) hoi. hieu qua cam xuc van hang di hoa viet".
• Adding a wildcard symbol may retrieve word variants: ((tu sang) OR (tu san)) ky ((lang xa) or (lang ha)) hoi. hieu qua cam xuc van hang di hoa viet*.
