Perhaps you should try some spelling variations:
vi transformed » _ transformed, a transformed, have transformed
idea transfer » den transfer, der transfer, sea transfer
transfer beim » transfer bei, transfers bei, transfer axiom
guias key » guias de
key idea » key ideas, very idea, key item
aguas do » aguas de, aguas del
do vi » do vih, dm vi, do v

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 beim cmacao ) OR ( aguas do vi transformed _ adocao ))~.
• Adding a wildcard symbol may retrieve word variants: (( guias key idea transfer beim cmacao ) or ( aguas do vi transformed _ adocao ))*.
