Perhaps you should try some spelling variations:
transport data » transport demand
sea transport » road transport, bus transport
transforms a » transforms _, transform a, transforms b
data macao » data macro
key idea » key ideas, very idea, key item
de idea » new idea, one idea
a acao » a adocao
luis a » luis f, luis c
a sea » _ sea, a set

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: (( luis ((de idea) OR (key idea)) transforms a acao ) OR ( luis a sea transport data macao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis ((de idea) OR (key idea)) transforms a acao ) or ( luis a sea transport data macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis ((de idea) OR (key idea)) transforms a acao ) or ( luis a sea transport data macao ))*.
