• Performing a fuzzy search may retrieve terms with similar spellings: ((vu dai) or (vu san)) ky ((tang van) OR (trong van)) hoi. hieu van cam xuc va dang te cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu dai) OR (vu san)) ky ((tang van) OR (trong van)) hoi. hieu van cam xuc va dang te cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu dai) or (vu san)) ky ((tang van) OR (trong van)) hoi. hieu van cam xuc va dang te cua tre".
• Adding a wildcard symbol may retrieve word variants: ((vu dai) or (vu san)) ky ((tang van) OR (trong van)) hoi. hieu van cam xuc va dang te cua tre*.
