transport aid » transport air, transport aimed, transport a
areas air » areas aida, areas a, areas act
guias f » guias de
f cash » _ cash, a cash, 4 cash
aid a » aid _, did a
2 ao » 2 a, 2 do, 2 ai
2 co » _ co, a co, 2 c

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: (( areas air sea transport aid a ) OR ( guias f cash transfers ((2 ao) OR (2 co)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas air sea transport aid a ) or ( guias f cash transfers ((2 ao) OR (2 co)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas air sea transport aid a ) or ( guias f cash transfers ((2 ao) OR (2 co)) ))*.
