Perhaps you should try some spelling variations:
land transfers » funds transfers, cash transfers, land transport
transport mode » transport modes
a transport » 3 transport, 4 transport, sea transport
value keys » values key
guias les » guide les, guias de
les land » lens land, altes land, does land
keys a » keys _, keynes a, keys rsa
mode a » mode ad, mode _, code 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: (( value keys a transport mode a ) OR ( guias les land transfers _ a ))~.
• Adding a wildcard symbol may retrieve word variants: (( value keys a transport mode a ) or ( guias les land transfers _ a ))*.
