Perhaps you should try some spelling variations:
medicion de » medicina de
caminos de » camino de
edicion y » edicion de
campo del » campo de, campos de, campo en
del lazo » del plazo, del lago, del lado
lazo pau » la pau
y campo » y campos, el campo, y cambio

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 y campo del lazo pau ; ) OR ( medicion de caminos de ((loas a) OR (las pau)) ; ))~.
• Adding a wildcard symbol may retrieve word variants: (( edicion y campo del lazo pau ; ) or ( medicion de caminos de ((loas a) or (las pau)) ; ))*.
