Perhaps you should try some spelling variations:
condiciones del » condiciones de, condicion de, condiciones _
edicion del » medicion del, edicion de, medicion de
campus per » campus de
campos del » campos de, campos el, campos e
campo der » campo de, campo del, campos de
la pau » la paz

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((condiciones del) or (edicion del)) ((campus per) or (((campo der) OR (campos del)))) la pau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((condiciones del) OR (edicion del)) ((campus per) OR (((campo der) OR (campos del)))) la pau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((condiciones del) or (edicion del)) ((campus per) or (((campo der) OR (campos del)))) la pau ;".
• Adding a wildcard symbol may retrieve word variants: ((condiciones del) or (edicion del)) ((campus per) or (((campo der) OR (campos del)))) la pau ;*.
