Perhaps you should try some spelling variations:
transform tvdft » transform fft, transform test
transfer costs » transport costs, transfer amounts
den transfer » gene transfer, heat transfer, data transfer
costs 5 » costs _, costs 4, costs a
luis 2 » luis f, luis c, luis e
luis a » luis f, luis c
luis m » luisa m, luis f, luis c
m den » um den, om den, m dent

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 2) OR (luis a)) leaders transform tvdft marc ) OR ( luis m den transfer costs 5 ))~.
• Adding a wildcard symbol may retrieve word variants: (( ((luis 2) or (luis a)) leaders transform tvdft marc ) or ( luis m den transfer costs 5 ))*.
