Perhaps you should try some spelling variations:
transfer costs » transport costs, transfer amounts
gene transfer » wire transfer, heat transfer, file transfer
data transfer » cash transfer, heat transfer
bei carl » iii carl
f gene » _ gene, a gene, e gene
luis i » luis c, luis a, luis e
i data » ii data, ai data, 2 data

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 f gene transfer ((bei carl) OR (wei carol)) ) OR ( luis i data transfer costs _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis f gene transfer ((bei carl) OR (wei carol)) ) or ( luis i data transfer costs _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis f gene transfer ((bei carl) OR (wei carol)) ) or ( luis i data transfer costs _ ))*.
