Perhaps you should try some spelling variations:
based transfers » basin transfers, cash transfers, water transfers
idea transport » ideas transport, sea transport, de transport
transport code » transport mode, transport modes, transport model
land transfers » funds transfers, cash transfers, land transport
vague key » value keys, sage key, vague de
key idea » key ideas, very idea, key item
guias de » guia de, guide de, aguas de
code a » code _, code 2

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: (( vague key idea transport code a ) OR ( guias de ((based transfers) OR (land transfers)) _ a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( vague key idea transport code a ) or ( guias de ((based transfers) OR (land transfers)) _ a ))~".
• Adding a wildcard symbol may retrieve word variants: (( vague key idea transport code a ) or ( guias de ((based transfers) OR (land transfers)) _ a ))*.
