Perhaps you should try some spelling variations:
mediaciones en » meditaciones en, mediciones en, mediaciones e
a campos » y campos, a campo, _ campos
en campo » el campo, un campo, del campo
campo en » campo de, campo y
la pau » la paz
e loa » de loa, e lona, e la
adiccion » adicion, accion, ficcion

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: (( adiccion a campos ((e loa) OR (es la)) pau ; ) OR ( mediaciones en campo en la pau ; ))~.
• Adding a wildcard symbol may retrieve word variants: (( adiccion a campos ((e loa) or (es la)) pau ; ) or ( mediaciones en campo en la pau ; ))*.
