des transport » des transports, de transport, den transport
systems gross » systems cross, systems across, systems growth
transformed a » transformed _, transformed 1, transformer 1
aguas del » aguas de, aguas do
values a » values _
del has » del caso
a acao » a adocao
a des » a der, a das

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( values a des transport systems gross ) OR ( aguas del has transformed a acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( values a des transport systems gross ) OR ( aguas del has transformed a acao ))*.
