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