Perhaps you should try some spelling variations:
water transport » air transport, water transfer
transport note » transport notes, transport noise, transport code
guias use » gas use, gis use, guias de
use water » unsafe water
key idea » key ideas, very idea, key item
de idea » new idea, one idea
note 1 » note _

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: (( aguas ((de idea) OR (key idea)) transport note 1 ) OR ( guias use water transport _ a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas ((de idea) OR (key idea)) transport note 1 ) or ( guias use water transport _ a ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas ((de idea) OR (key idea)) transport note 1 ) or ( guias use water transport _ a ))*.
