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