Perhaps you should try some spelling variations:
transfer beim » transfer bei, transfers bei, transfer axiom
transport et » transport en, transport _, transport a
bus users » gas users, bus use
de ideas » di ideas, dead ideas, new ideas
de idea » new idea, key idea, one idea
guia » gua, gui, gaia
heat » head

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: (( guia ((de ideas) OR (de idea)) transport et acao ) OR ( bus users heat transfer beim cocoa ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guia ((de ideas) OR (de idea)) transport et acao ) or ( bus users heat transfer beim cocoa ))~".
• Adding a wildcard symbol may retrieve word variants: (( guia ((de ideas) OR (de idea)) transport et acao ) or ( bus users heat transfer beim cocoa ))*.
