Perhaps you should try some spelling variations:
transport system » transport sector
a transformed » _ transformed, _ transformer, a transforming
de transport » sea transport, free transport, bus transport
system pt » system 1
1 macro » _ macro, 2 macro, 3 macro
a macro » _ macro
e a » et a

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: (( agua _ de transport system pt ) OR ( agua e a transformed ((1 macro) OR (a macro)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua _ de transport system pt ) or ( agua e a transformed ((1 macro) OR (a macro)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( agua _ de transport system pt ) or ( agua e a transformed ((1 macro) OR (a macro)) ))*.
