Perhaps you should try some spelling variations:
ediciones del » ediciones de, edicion del, condiciones del
medicion de » medicina de
campos raul » campa raul, campos manuel, campos bravo
del campo » el campo, de campo, del cambio
de campos » de campo, de caminos, de cambios
campo y » campo de
a paul » _ paul
a pau » la pau, a paz

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: (( ediciones del campo y la paz ; ) OR ( medicion de campos raul ((a pau) OR (a paul)) ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ediciones del campo y la paz ; ) or ( medicion de campos raul ((a pau) OR (a paul)) ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( ediciones del campo y la paz ; ) or ( medicion de campos raul ((a pau) OR (a paul)) ; ))*.
