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