Perhaps you should try some spelling variations:
transform primer » transform order, transform power, transform fourier
masse transform » make transform, cosine transform
mass transfer » cash transfer, basin transfer, mass transport
primer 3 » primer _, primes 3, primers _
aguas de » aguas del, aguas do, vagues de
guias 3 » guias de
fairs 3 » fairs _, fairs a

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