Perhaps you should try some spelling variations:
medicion de » medicina de
adicion dde » adicion de, adicion del, adiccion de
dde campos » de campos, de campo, de campus
campo un » campo uni, campo juan, campora un
campo en » campo de, campo y
lao paz » la paz
de lao » de lazo, de lago, del lao

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 de ((campo un) OR (campo en)) las pau ; ) OR ( adicion dde campos de lao paz ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( medicion de ((campo un) OR (campo en)) las pau ; ) or ( adicion dde campos de lao paz ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( medicion de ((campo un) OR (campo en)) las pau ; ) or ( adicion dde campos de lao paz ; ))*.
