Perhaps you should try some spelling variations:
ediciones de » edicion de, condiciones de
edicion del » medicion del, edicion de, medicion de
del campos » del campo, de campos, del campus
caminos de » camino de
campos la » campos de
loa pau » la pau
la loa » la loca, la loma, la lola

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: (( edicion del campos la loa pau ; ) OR ( ediciones de caminos de la paz ; ))~.
• Adding a wildcard symbol may retrieve word variants: (( edicion del campos la loa pau ; ) or ( ediciones de caminos de la paz ; ))*.
