Perhaps you should try some spelling variations:
transport data » transport demand
transfer cost » transfer costs, transfer cash, transfer bot
far transfer » a transfer, gas transfer, water transfer
luis c » luis f
luis a » luis f
cost 5 » cost 15, cost _, cost 4
c bis » 1 bis, 2 bis, 6 bis
a far » a fair, a farm, _ far

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 c bis ((transport _) OR (transport data)) marc ) OR ( luis a far transfer cost 5 ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis c bis ((transport _) or (transport data)) marc ) or ( luis a far transfer cost 5 ))*.
