• Performing a fuzzy search may retrieve terms with similar spellings: tu ban ky ((nang xa) OR (lang xa)) hoi. ((thien van) or (thi van)) phan duc ban hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ban ky ((nang xa) OR (lang xa)) hoi. ((thien van) OR (thi van)) phan duc ban hanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ban ky ((nang xa) OR (lang xa)) hoi. ((thien van) or (thi van)) phan duc ban hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu ban ky ((nang xa) OR (lang xa)) hoi. ((thien van) or (thi van)) phan duc ban hanh vai cua tre*.
