Perhaps you should try some spelling variations:
transfers und » transfer und, transfers united, transfers made
transformed a » transformed _, transformed 1, transformer 1
und case » und care, und cash, id case
how have » how has
do have » who have
a acao » a adocao
guias » guia
arms » farms, aims, arts

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 _ arms transfers und case ) OR ( vagues ((do have) OR (how have)) transformed a acao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias _ arms transfers und case ) or ( vagues ((do have) OR (how have)) transformed a acao ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias _ arms transfers und case ) or ( vagues ((do have) OR (how have)) transformed a acao ))*.
