Perhaps you should try some spelling variations:
ediciones de » edicion de, condiciones de
campus peru » campus per, corpus peru, campos perez
de campus » del campus, de campos, de corpus
case pau » casas pau, case para, case la
de campo » de cambio
el campo » el cambio, el camino
la pau » la 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 de campus peru case pau ; ) OR ( medicion ((de campo) OR (el campo)) de la pau ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ediciones de campus peru case pau ; ) or ( medicion ((de campo) OR (el campo)) de la pau ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( ediciones de campus peru case pau ; ) or ( medicion ((de campo) OR (el campo)) de la pau ; ))*.
