Perhaps you should try some spelling variations:
transit systems » transport systems, transport system
1 transformed » _ transformed, a transformed, vi transformed
transformed a » transformed _, transformed 1, transformer 1
systems fair » systems fail, systems dairy, systems farm
den transit » de transit, der transit, new transit
aguas der » aguas de, aguas del, aguas do
a macao » a macro, _ macao
der 1 » der 10, der 11, der 12

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: (( agua _ den transit systems fair ) OR ( aguas der 1 transformed a macao ))~.
• Adding a wildcard symbol may retrieve word variants: (( agua _ den transit systems fair ) or ( aguas der 1 transformed a macao ))*.
