Perhaps you should try some spelling variations:
cosine transform » alone transform, could transform, loeve transform
transform cities » transforming cities, transform cote, transform coding
transform crisis » transfer crisis, transport crisis, transform pairs
can transform » _ transform
cities a » cities _
aguas do » aguas de, aguas del
crisis a » crisis _

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: (( guias _ can transform cities a ) OR ( aguas do cosine transform crisis a ))~.
• Adding a wildcard symbol may retrieve word variants: (( guias _ can transform cities a ) or ( aguas do cosine transform crisis a ))*.
