• Performing a fuzzy search may retrieve terms with similar spellings: vu ((khach ly) or (khich le)) vang xa hoi. hieu va cam ((tuc van) OR (thuc van)) danh du cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((khach ly) OR (khich le)) vang xa hoi. hieu va cam ((tuc van) OR (thuc van)) danh du cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((khach ly) or (khich le)) vang xa hoi. hieu va cam ((tuc van) OR (thuc van)) danh du cua te".
• Adding a wildcard symbol may retrieve word variants: vu ((khach ly) or (khich le)) vang xa hoi. hieu va cam ((tuc van) OR (thuc van)) danh du cua te*.
