transformer 1 » transformer _, transformed _
aguas help » aguas del
can across » can cross, can access, ct across
help road » help good, help lead
1 macao » _ macao, 1 macro, 2.1 macao
et a » et la, e 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: (( aguas help road transport can across ) OR ( agua ((et a) OR (et al)) transformer 1 macao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aguas help road transport can across ) or ( agua ((et a) OR (et al)) transformer 1 macao ))~".
• Adding a wildcard symbol may retrieve word variants: (( aguas help road transport can across ) or ( agua ((et a) OR (et al)) transformer 1 macao ))*.
