Perhaps you should try some spelling variations:
le editores » de editores, los editores, b editores
y mediacion » la mediacion, de mediacion
y medicos » y medicion, de medicos, y medianos
y autores » y actores, de autores
y medios » y medio
ou le » ou la, ou de
onu y » ong y, one y

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: (( ((y medicos) OR (y medios)), ou le editores. ) OR ( y mediacion, onu y autores. ))~.
• Adding a wildcard symbol may retrieve word variants: (( ((y medicos) or (y medios)), ou le editores. ) or ( y mediacion, onu y autores. ))*.
