Perhaps you should try some spelling variations:
data transfer » cash transfer, heat transfer
transfer der » transfer fees, transfer _
based case » based care, base case, based phase
bad case » id case, d case, und case
luis e » luis f, luis c, luis a
e data » e datas, age data, cge data
guias » guia
cmacao » cacao, macao

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 ((bad case) OR (based case)) transformed _ acao ) OR ( luis e data transfer der cmacao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias ((bad case) OR (based case)) transformed _ acao ) or ( luis e data transfer der cmacao ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias ((bad case) OR (based case)) transformed _ acao ) or ( luis e data transfer der cmacao ))*.
