Perhaps you should try some spelling variations:
transfer axiom » transfer from, transfer asia
idea transfer » den transfer, der transfer, sea transfer
a transformed » _ transformed, _ transformer, a transforming
guias key » guias de
key idea » key ideas, very idea, key item
aguas do » aguas de, aguas del
do a » do _, do i, dr 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 key idea transfer axiom cmacao ) OR ( aguas do a transformed _ adocao ))~.
• Adding a wildcard symbol may retrieve word variants: (( guias key idea transfer axiom cmacao ) or ( aguas do a transformed _ adocao ))*.
