transform force » transform fourier, transform cote, transform order
haar transform » can transform, data transform, make transform
del cosine » del cine
aguas del » aguas de, aguas do

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 _ haar transform force la ) OR ( aguas del cosine transform crisis a ))~.
• Adding a wildcard symbol may retrieve word variants: (( guias _ haar transform force la ) or ( aguas del cosine transform crisis a ))*.
