• Performing a fuzzy search may retrieve terms with similar spellings: tu dan ky ((nang lai) OR (nang tai)) hoi. hieu su chat luc va hanh vai ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ky ((nang lai) OR (nang tai)) hoi. hieu su chat luc va hanh vai ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu dan ky ((nang lai) OR (nang tai)) hoi. hieu su chat luc va hanh vai ((cua te) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: tu dan ky ((nang lai) OR (nang tai)) hoi. hieu su chat luc va hanh vai ((cua te) or (cua tu))*.
