systems versus » systeme versus, systems excursus
data transfer » cash transfer, heat transfer
a transformed » _ transformed, _ transformer, a transforming
transformed 1 » transformed _, transformer 1, transformed a
vagues de » vague de, values de, langues de
vagues do » aguas do, vague de
de data » e data, wide data, de datos
do a » do _, do i, dr a
acao » cacao, macao, cao

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: (( vagues de data transfer systems versus ) OR ( vagues do a transformed 1 acao ))~.
• Adding a wildcard symbol may retrieve word variants: (( vagues de data transfer systems versus ) or ( vagues do a transformed 1 acao ))*.
