Perhaps you should try some spelling variations:
transfer learning » teacher learning
data transfer » cash transfer, heat transfer
learning clay » learning can, learning clil, learning case
transport a » transport _, transport data
a ideas » 2 ideas, 3 ideas, 6 ideas
a mark » a markt, a mask, d mark
f data » 2 data, 1 data, dlf data

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: (( luis ((a ideas) OR (_ ideas)) transport a mark ) OR ( luis f data transfer learning clay ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis ((a ideas) OR (_ ideas)) transport a mark ) or ( luis f data transfer learning clay ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis ((a ideas) OR (_ ideas)) transport a mark ) or ( luis f data transfer learning clay ))*.
