• Performing a fuzzy search may retrieve terms with similar spellings: vu cac ky tang xa hoi. hieu nghe nam thuc dang thanh vi ((cua te) or (((cua tu) OR (cua su))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu cac ky tang xa hoi. hieu nghe nam thuc dang thanh vi ((cua te) OR (((cua tu) OR (cua su))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu cac ky tang xa hoi. hieu nghe nam thuc dang thanh vi ((cua te) or (((cua tu) OR (cua su))))*".
