Perhaps you should try some spelling variations:
transfer pairs » transform pairs, transfer prices, transfer points
haar transform » can transform, data transform, make transform
mass transfer » cash transfer, basin transfer, mass transport
guias de » guia de, guide de, aguas de
de haar » de haan, de haas, de hablar
guide a » guide _
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 a mass transfer pairs 3 ))~.
• Adding a wildcard symbol may retrieve word variants: (( guias de haar transform _ a ) or ( guide a mass transfer pairs 3 ))*.
