Perhaps you should try some spelling variations:
haar transform » can transform, data transform, make transform
transform haar » transform pairs, transform your, transform our
guias de » guia de, guide de, aguas de
de haar » de haan, de haas, de hablar
a masse » a mass, a massive, a master
b masse » _ masses, de masse, 3 masses

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