Perhaps you should try some spelling variations:
ideal transform » ideas transform, ideas transport, ideals transforming
transform fft » transform tvdft, transform cote, transform test
das transfer » cash transfer, data transfer, mass transfer
gas transfer » cash transfer, mass transfer, a transfer
areas can » areas case, areas cash, areas coal
can ideal » can deal, than ideal, das ideal
guias 2 » guias de
fft _ » fit _, fat _, dft _
4 ao » 4 aoi, 4 a, 4 do

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( areas can ideal transform fft _ ) OR ( guias 2 ((das transfer) OR (gas transfer)) 4 ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas can ideal transform fft _ ) or ( guias 2 ((das transfer) OR (gas transfer)) 4 ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas can ideal transform fft _ ) or ( guias 2 ((das transfer) OR (gas transfer)) 4 ao ))*.
