Perhaps you should try some spelling variations:
acciones de » lecciones de, accion de, accidentes de
medicion de » medicina de
campo del » campos de, campo en
de campo » de cambio, el campo
de lorna » de lorca, de lona, de loria
plan a » plan _, plan d, plan 9
plan e » plan de, plan _, plana de

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: (( acciones de campo de lorna pau ; ) OR ( medicion de campo del ((plan a) OR (plan e)) ; ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( acciones de campo de lorna pau ; ) or ( medicion de campo del ((plan a) OR (plan e)) ; ))~".
• Adding a wildcard symbol may retrieve word variants: (( acciones de campo de lorna pau ; ) or ( medicion de campo del ((plan a) OR (plan e)) ; ))*.
