Perhaps you should try some spelling variations:
idea transport » ideas transport, sea transport, de transport
based transfer » based transfers, basin transfer, basin transfers
value keys » values key
keys idea » key idea, key ideas
guias les » guide les, guias de
les based » les bases, aes based, ses based
mode a » mode ad, mode _, mode 1
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: (( value keys idea transport ((mode a) OR (code a)) ) OR ( guias les based transfer _ a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( value keys idea transport ((mode a) OR (code a)) ) or ( guias les based transfer _ a ))~".
• Adding a wildcard symbol may retrieve word variants: (( value keys idea transport ((mode a) OR (code a)) ) or ( guias les based transfer _ a ))*.
