Perhaps you should try some spelling variations:
mass transfer » cash transfer, basin transfer, mass transport
transform fft » transform tvdft, transform cote, transform test
transfer 3 » transfer _, transfer 4, transfer a
areas co » areas coal, areas act, areas can
guide de » guide _, guide a, guide 2
guide 1 » guide _, guide a
fft a » fft 4, fft _, sft a

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 _ transform fft a ) OR ( ((guide de) OR (guide 1)) mass transfer 3 a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas co _ transform fft a ) or ( ((guide de) OR (guide 1)) mass transfer 3 a ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas co _ transform fft a ) or ( ((guide de) OR (guide 1)) mass transfer 3 a ))*.
