Perhaps you should try some spelling variations:
ocean transport » urban transport, green transport, sea transport
transport data » transport demand
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
c ocean » _ ocean, 1 ocean, 3 ocean
a acao » a adocao
luis c » luis f

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 c ocean 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 c ocean transport data macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis ((de idea) OR (key idea)) transforms a acao ) or ( luis c ocean transport data macao ))*.
