Perhaps you should try some spelling variations:
haar transform » can transform, data transform, make transform
transfer risks » transfer risk
risk transfer » cash transfer
guias do » guia do, guias de, guia de
guias a » guias de
conte 2 » conte di
conte 3 » conte di
do risk » d risk, de risk, dam risk
a haar » _ haar, a hazard

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 a haar transform ((conte 2) OR (conte 3)) ) OR ( guias do risk transfer risks _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias a haar transform ((conte 2) OR (conte 3)) ) or ( guias do risk transfer risks _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias a haar transform ((conte 2) OR (conte 3)) ) or ( guias do risk transfer risks _ ))*.
