Perhaps you should try some spelling variations:
based transfers » basin transfers, cash transfers, land transfers
meet africa's » west africa's, meeting africa's, east africa's
transport atd » transport data, transport a, transport air
guias de » guia de, guide de, aguas de
de based » dge based, de base, de bases
atd a » add a, aid a, ahd a
2 co » _ co, a co
aguas » agus, agua

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 meet africa's transport atd a ) OR ( guias de based transfers ((2 co) OR (2 c)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas meet africa's transport atd a ) or ( guias de based transfers ((2 co) OR (2 c)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas meet africa's transport atd a ) or ( guias de based transfers ((2 co) OR (2 c)) ))*.
