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