Perhaps you should try some spelling variations:
dos editores » los editores, dos escritores, los auditores
en medicina » de medicina, la medicina
de editores » de auditores, b editores, y editores
y medicina » de medicina, la medicina, y mediana
duke dos » de dos
tu de » tu me, ou de, du de
medianas, » mediana,, mediante,, medicas,

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 medicina) OR (en medicina)), tu de editores. ) OR ( y medianas, duke dos editores. ))~.
• Adding a wildcard symbol may retrieve word variants: (( ((y medicina) or (en medicina)), tu de editores. ) or ( y medianas, duke dos editores. ))*.
