Perhaps you should try some spelling variations:
transform tvdft » transform fft, transform test
make transform » make transport, can transform, we transform
transfer 3 » transfer _, transfer 4, transfer a
areas co » areas coal, areas act, areas can
de gases » de bases, f gases, de gaer
co make » can make, you make, who make
_ gases » _ games, _ gates, f gases
3 ao » 3 a, 3 co, 3 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 co make transform tvdft a ) OR ( guias ((de gases) OR (_ gases)) transfer 3 ao ))~.
• Adding a wildcard symbol may retrieve word variants: (( areas co make transform tvdft a ) or ( guias ((de gases) or (_ gases)) transfer 3 ao ))*.
