Perhaps you should try some spelling variations:
transform tvdft » transform fft, transform test
transform dft » transform fft, transform cote, transform test
gas transfer » cash transfer, mass transfer, a transfer
transfer 3 » transfer _, transfer 4, transfer a
areas can » areas case, areas cash, areas coal
can ideas » las ideas, own ideas, un ideas
guias 2 » guias de
2 gas » _ gas, 3 gas
3 do » _ do, 3 d, 1 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 ideas ((transform dft) OR (transform tvdft)) _ ) OR ( guias 2 gas transfer 3 do ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas can ideas ((transform dft) OR (transform tvdft)) _ ) or ( guias 2 gas transfer 3 do ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas can ideas ((transform dft) OR (transform tvdft)) _ ) or ( guias 2 gas transfer 3 do ))*.
