Perhaps you should try some spelling variations:
transform tvdft » transform fft, transform test
transform dft » transform fft, transform cote, transform test
das transfer » gas transfer, cash transfer, data transfer
transfer a » transfer _, transfer 3, transfer 4
areas can » areas case, areas cash, areas coal
can ideas » las ideas, own ideas, un ideas
guias f » guias de
f das » 1 das, 2 das, 3 das
a o » a co

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 ideas ((transform dft) OR (transform tvdft)) _ ) OR ( guias f das transfer a o ))~.
• Adding a wildcard symbol may retrieve word variants: (( areas can ideas ((transform dft) or (transform tvdft)) _ ) or ( guias f das transfer a o ))*.
