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