Perhaps you should try some spelling variations:
medicion el » medicion del, mediacion el, medicion e
edicion el » edicion del, edicion en, edicion e
el camino » el cambio
el campo » el cambio
loca pau » loca a
campo a » campo la, campo y, campo _
local a » local la, local y, local una

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: (( medicion el campo a ((loca pau) OR (local a)) ; ) OR ( edicion el camino de la paz ; ))~.
• Adding a wildcard symbol may retrieve word variants: (( medicion el campo a ((loca pau) or (local a)) ; ) or ( edicion el camino de la paz ; ))*.
