Perhaps you should try some spelling variations:
based transfers » basin transfers, cash transfers, land transfers
transport code » transport mode, transport modes, transport model
one idea » one sided, new idea, one side
guias de » guia de, guide de, aguas de
de based » dge based, de base, de bases
de idea » new idea, key idea
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 ((de idea) OR (one idea)) transport code a ) OR ( guias de based transfers _ a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( vague ((de idea) OR (one idea)) transport code a ) or ( guias de based transfers _ a ))~".
• Adding a wildcard symbol may retrieve word variants: (( vague ((de idea) OR (one idea)) transport code a ) or ( guias de based transfers _ a ))*.
