aguas air » areas air
guias f » guias de
f based » kf based, rf based, 3 based

2 do » _ do, 2 co, 1 do
2 de » 2 die, 2 der, _ de

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