Perhaps you should try some spelling variations:
transform tvdft » transform test
gases transfer » mass transfer, based transfer, gas transfer
transform fft » transform cote, transform test, transform _
transfer 3 » transfer _, transfer 4, transfer a
areas co » areas coal, areas act, areas can
co ideas » core ideas, two ideas, box ideas
guias f » guias de
f gases » _ gases

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 ideas ((transform fft) OR (transform tvdft)) 4 ) OR ( guias f gases transfer 3 a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas co ideas ((transform fft) OR (transform tvdft)) 4 ) or ( guias f gases transfer 3 a ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas co ideas ((transform fft) OR (transform tvdft)) 4 ) or ( guias f gases transfer 3 a ))*.
