Perhaps you should try some spelling variations:
water transport » air transport, water transfer
transport note » transport notes, transport noise, transport code
transport a » transport _, transport data
guias use » gas use, gis use, guias de
use water » unsafe water
del idea » del lider, del dia, new idea
de idea » new idea, key idea, one idea
note a » note _, note 1, note 2
a a » a la

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