Perhaps you should try some spelling variations:
condiciones del » condiciones de, condicion de, condiciones _
ediciones del » ediciones de, edicion del, ediciones area
campus per » campus de
campo per » campo perez, campo para, campo de
campo der » campo de, campo del, campos del
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: ((ediciones del) OR (condiciones del)) ((((campo per) or (campus per))) or (campo der)) la pau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ediciones del) OR (condiciones del)) ((((campo per) OR (campus per))) OR (campo der)) la pau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ediciones del) OR (condiciones del)) ((((campo per) or (campus per))) or (campo der)) la pau ;".
• Adding a wildcard symbol may retrieve word variants: ((ediciones del) OR (condiciones del)) ((((campo per) or (campus per))) or (campo der)) la pau ;*.
