Perhaps you should try some spelling variations:
transform tvdft » transform test
transfer costs » transport costs, transfer amounts
transform fft » transform cote, transform test, transform _
den transfer » gene transfer, heat transfer, data transfer
costs a » costs _, costs 4
luis a » luis f, luis c
a den » _ den, a der, a des

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( luis _ ideas ((transform fft) OR (transform tvdft)) marc ) or ( luis a den transfer costs a ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( luis _ ideas ((transform fft) OR (transform tvdft)) marc ) OR ( luis a den transfer costs a ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis _ ideas ((transform fft) OR (transform tvdft)) marc ) or ( luis a den transfer costs a ))*".
