• Performing a fuzzy search may retrieve terms with similar spellings: vu san ky lang van hoi. hieu vien cac du gia ((thanh ca) OR (thanh ha)) ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky lang van hoi. hieu vien cac du gia ((thanh ca) OR (thanh ha)) ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky lang van hoi. hieu vien cac du gia ((thanh ca) OR (thanh ha)) ((cua tre) or (cua triet))*".
