Perhaps you should try some spelling variations:
transform fair » transform pairs, transform haar, transform family
haar transform » data transform, make transform, hadamard transform
transform fft » transform tvdft, transform cote, transform test
can transform » _ transform
guide de » guide _, guide a, guide 1
fair 4 » fair _, fair 5, fair 6
fft 3 » fft 4, fft _, sft 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 _ haar transform fft 3 ) OR ( ((guia de) OR (guide de)) can transform fair 4 ))~.
• Adding a wildcard symbol may retrieve word variants: (( guias _ haar transform fft 3 ) or ( ((guia de) or (guide de)) can transform fair 4 ))*.
