Perhaps you should try some spelling variations:
transformation a » transformation _
file transfer » wire transfer, risk transfer, food transfer
vagues de » vague de, values de, langues de
de file » de fele, do file, code file
del i » del ii
a can » _ can, 3 can, 4 can
de i » des i, de ic, de id

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: (( gui ((de i) OR (del i)) transformation a can ) OR ( vagues de file transfer _ 3 ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( gui ((de i) OR (del i)) transformation a can ) or ( vagues de file transfer _ 3 ))~".
• Adding a wildcard symbol may retrieve word variants: (( gui ((de i) OR (del i)) transformation a can ) or ( vagues de file transfer _ 3 ))*.
