Perhaps you should try some spelling variations:
masse transform » mass transfer, cosine transform
haar transform » can transform, data transform, hadamard transform
make transform » make transport, can transform, we transform
guias de » guia de, aguas de, guia do
guide de » guide _, guide a, guide 1
de haar » de haan, de haas, de hablar
pairs 3 » pairs _, pairs 4, fairs 3

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 de haar transform _ a ) OR ( guide de ((masse transform) OR (make transform)) pairs 3 ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias de haar transform _ a ) or ( guide de ((masse transform) OR (make transform)) pairs 3 ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias de haar transform _ a ) or ( guide de ((masse transform) OR (make transform)) pairs 3 ))*.
