Perhaps you should try some spelling variations:
transfer fees » transfer from
transform fft » transform tvdft, transform cote, transform test
fees carl » des carl
dlf data » rdf data
imf data » imf's data, rdf data
luis a » luis f, luis c
a heat » a heart, _ heat, a head

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: (( luis a heat transfer fees carl ) OR ( luis ((dlf data) OR (imf data)) transform fft _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis a heat transfer fees carl ) or ( luis ((dlf data) OR (imf data)) transform fft _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis a heat transfer fees carl ) or ( luis ((dlf data) OR (imf data)) transform fft _ ))*.
